About This Product

Napoleon Ascent X 42" Direct Vent Gas Fireplace

The Napoleon Ascent X 42" is a direct vent gas fireplace that comes ready to enjoy: a hand-painted split oak log set with glowing embers and ember-bed lighting, a heat-circulating blower, the F60 thermostatic remote and a premium safety barrier are all included, from $3,799. It is rated 30,000 BTU/hr on natural gas or propane with pilot-on-demand electronic ignition, vents through a 5" / 8" pipe off the top or the back, frames into a 42-1/2" wide, 18-9/16" deep opening, and carries Napoleon's President's Lifetime Limited Warranty.

Choose the 42" if you want a wider traditional oak log fire with the blower and remote already in the box, matte black interior panels as standard, and the option to dress the firebox with brick or reflective porcelain panels. It is approved for bedrooms and bathrooms and certified for mobile homes.

It is not right for you if you want a contemporary linear flame. The Ascent X is a traditional oak log fire with the blower and remote already in the box.

Specifications

The framed opening is 42-1/2" wide, 41-1/8" high and 18-9/16" deep, and the fireplace itself measures 42" wide by 34-5/8" high by 18-5/16" deep. The enclosure needs at least 52-5/8" of height above the base. The face is finished in non-combustible material over the facing board that comes with the fireplace, and the finish may stand out up to 4" from the safety barrier. Mantel clearances depend on the mantel's depth and are charted in section 10.5 on page 50 of the installation manual. The vent pipe needs 3" above and 1" at the sides of horizontal runs and 1" around vertical runs, and the fireplace takes a 1/2" gas line with a flex connector (3/8" without one) and a hard-wired 115 V supply.

How the Ascent X 42" compares to the 36"

Both Ascent X sizes include the split oak log set, ember-bed lighting, the blower, the F60 remote and the safety barrier. The 42" is rated 30,000 BTU/hr, vents on a 5" / 8" pipe and frames into a 42-1/2" wide opening, from $3,799; the 36" is rated 26,000 BTU/hr on natural gas, vents on a 4" / 7" pipe and frames into a 35-1/2" opening.

Answers to common questions

What venting does the Ascent X 42" need?

It is a direct vent fireplace on a 5" exhaust / 8" air-intake pipe, off the top or the back of the unit, run out through a wall or up through the roof: up to 20 ft horizontally and up to 40 ft vertically. Use one brand of pipe throughout — Napoleon (Wolf Steel), Metal-Fab, BDM, Simpson Dura-Vent or Selkirk Direct Temp — and do not mix rigid and flexible pipe. Napoleon's wall terminals are the GD422-1, GD422R-2 and ST58U-1, with roof kits for pitched and flat roofs. The vent run and termination are ordered separately and sized to your installation; the insulated sleeve for a rear-vent run comes with the fireplace, and the outside terminal clearances are listed on page 17 of the installation manual. A power vent kit can be used on a top-vent installation.

What’s included, what’s required, and what’s optional?
  • Included in the box: Split oak log set with glowing embers, charcoal embers and ember-bed glass — the Ascent X is sold with its log set; Ember-bed lighting (Night Light); Heat-circulating blower with variable-speed control; Electronic pilot-on-demand ignition with the F60 thermostatic remote control; 5 mm ceramic glass door with premium safety barrier screen; Non-combustible facing board and the insulated sleeve for a rear-vent run; Interior panels in matte black, included as standard — the decorative panel kits are an optional upgrade.
  • Required to complete the installation, purchased separately: Venting - 5" / 8" direct vent pipe and a wall or roof termination sized for your run (see pg 13 in the installation manual); Electrical - a grounded 115 V supply, hard-wired to the fireplace; Gas Line - a gas supply to the fireplace's manual shut-off valve - 1/2" if the fireplace is fitted with a flex connector, 3/8" without one.
  • Optional: Decorative interior panels (choose above), a vertical or external wall venting package, heat management (Universal Heat Management or the Hot Air Distribution Kit), a power vent adaptor kit, decorative fronts and finishing trims, a wall thermostat and the eFIRE Bluetooth controller — the fireplace operates fully without any of them.
Can I mount a TV above it?

Yes, with planning. Napoleon draws the TV placements above the Ascent X 42" — flush, recessed and partially recessed, with or without a mantel — in section 10.6 on page 51 of the installation manual, and recommends the optional Universal Heat Management kit for any TV above the fireplace; some of those placements are not acceptable unless it is installed. The kit also lowers the temperature above the fireplace and reduces the mantel clearances charted on page 50. It goes in with the fireplace, on a top-vent installation. Always stay within your TV maker's own temperature limits.

Where can it be installed?

Indoors, including bedrooms, bathrooms and bed-sitting rooms, and it is certified for mobile and manufactured homes where local codes allow (fastened in place). It is rated to 4,500 ft, with the input reduced above that. Keep furniture and other objects at least 48" from the front, and do not run it below freezing.

Will it work during a power outage?

Yes. The pilot-on-demand ignition can run from a USB power bank (not included) plugged into the control board in place of its power supply, so the fireplace still lights when the power is out.

What gas and electrical connections does it need?

A natural gas or propane line to the fireplace's manual shut-off valve (1/2" if it is fitted with a flex connector, 3/8" without one), connected and tested before the wall is finished — natural gas at 4.5" to 7" w.c. inlet pressure, propane at 11" to 13" w.c. Electrically it is hard-wired to a grounded 115 V, 60 Hz supply. It can be converted between natural gas and propane with Napoleon's certified conversion kit.

Does buying from The Torch Guys affect my Napoleon warranty?

No. The Torch Guys is an authorized Napoleon dealer, so the President's Lifetime Limited Warranty applies in full, and we file claims with Napoleon for you. The firebox, burner, PHAZER logs and embers and the ceramic glass (against heat breakage) are covered for as long as you own the fireplace — parts free for the first 10 years, then at half of retail; blowers, valves, remotes and other electrical parts and the labour are covered for the first year. Coverage starts on the installation date.

Warranty

In the unlikely event your product experiences a defect, our technical team will guide you through the manufacturer’s warranty process. Here is a general outline of what to expect.

Due to the technical nature of our products, the manufacturer must perform troubleshooting to process a warranty claim. Your installer will need to troubleshoot the problem on-site while working in tandem with our technical team. If troubleshooting leads to what The Torch Guys deems as a defective part, we will submit a warranty claim to the manufacturer on your behalf. Before we submit the claim, we will ask you to review the terms and confirm your consent to proceed.

Once the claim is submitted, the manufacturer will review it and either approve or deny it. If they have all the information and accept the claim, your warranty replacement part(s) will begin processing for shipment. If, for any reason, the claim is denied or we need more information, we will notify you as soon as possible.

All warranties are processed as exchanges. You can expect to receive a prepaid return label for the defective part(s), which must be returned within 30 days of receiving the warranty replacement(s).

Warranty claims can take anywhere from 1-4 weeks to process, depending on the season. Given the length of time claims can take, we recommend you fire up your unit in late summer/early fall to ensure your existing fireplace is in good working order for the winter season.
