A built-in gas fireplace is sized by the manufacturer’s framing (rough opening) spec — the exact framing drawing for this model is in the manufacturer’s installation manual — see the Manufacturer Documents tab.
- New installs (direct-vent & vent-free) — confirm your wall or chase has the width, height, and depth the framing spec calls for, and plan the vent route for direct-vent models (through an exterior wall or the roof). Vent-free models need no vent at all.
- Inserts — measure your existing firebox in four places: front width, rear width, height, and depth, plus your chimney height. Compare against the insert’s minimum opening in Specifications.
- See-through & corner models — check the required wall depth between finished faces on both sides.

Official documents from Majestic. These are the drawings to check before you frame the opening — they are the manufacturer's current revision, hosted on their own site.
Documents are published by the manufacturer and can be revised without notice. If anything in them conflicts with what you see here, the manufacturer's document is the one that governs the install.
Buying online and hiring a local installer is standard practice — the manufacturer’s warranty applies in full. Line up your installer before you order: send them this model’s spec sheet, agree the venting route, then add the exact venting and accessories they specify in the configurator so everything arrives together.
Typical professional installation runs $800–$2,000 for inserts and simple direct-vent runs, up to $3,500+ for complex venting (labor and permits vary by region). Vent-free models with an existing gas line run less.
How to find an NFI-certified installer, the questions to ask, permits, and what to do if a local dealer won’t touch online-bought equipment: read the installation guide.
Free freight shipping within the contiguous US (Alaska, Hawaii, and Canada by quote). Fireplaces ship factory-new via FedEx, UPS, or AIT freight — you’ll receive tracking by email, and for freight deliveries the carrier calls ahead to schedule. Typical transit is 3–6 business days once shipped.
At delivery: inspect before you sign. Note any damage on the delivery receipt and contact us within 24 hours with photos — confirmed transit damage is repaired or replaced at no cost to you. Full walkthrough: how freight delivery works.
Returns: fireplaces and their configured accessories (log sets, liners, venting) are ordered from the manufacturer to your specification. You can change or cancel within 48 hours of ordering; after shipment, returns are handled with the manufacturer case by case — contact us first and we’ll make it right. Full details in our refund policy.
Every fireplace we sell is factory-new from an authorized dealer and covered by the manufacturer’s warranty. Majestic warrants key components like the firebox and heat exchanger for extended periods — many with limited lifetime coverage on the combustion chamber — with shorter terms on burners, glass, electronics, and finishes (see the owner’s manual for this model’s exact schedule).
Keep your order confirmation as proof of purchase and register your unit with the manufacturer after installation. Need help with a claim? Contact us — we’ll coordinate with the manufacturer for you.

Frequently Asked
Does this fireplace need a chimney?
Yes. A B-vent fireplace draws combustion air from the room and exhausts vertically through a B-vent flue to the roof, so it needs a vertical vent run. It is not sealed behind glass the way a direct-vent unit is.
Can I install this myself?
Plan on a licensed professional for the gas work. In most jurisdictions connecting gas is permitted work that has to be done by a licensed gas fitter and signed off at a final inspection, and doing it yourself can void both the manufacturer warranty and your homeowner insurance. Manufacturers say the same thing — FireRock, for example, instructs installers to "consult with local building and zoning authorities regarding the need for proper permitting" before construction starts. Framing and finish work is often owner-supplied; the gas connection and the final inspection are not.
How do I know it will fit the space I have?
Work from the framed opening rather than the finished wall. Manufacturers publish a framing dimension and a minimum enclosure height, and both have to be right before the finish material goes on — Napoleon, for example, specifies a framing depth range and a minimum unobstructed enclosure height for its multi-view units. If you send us your rough opening we will check it against the manual for that model.
Can I mount a TV above this fireplace?
Sometimes, but it depends on the model and how you finish the wall. There is no blanket ban — manufacturers frame it as a clearance and heat question. Napoleon's manual puts it plainly: keep clearances to combustibles when building a mantel or shelf above the unit, because "elevated temperatures on the wall or in the air above the appliance can cause melting, discolouration or damage to decorations, a TV or other electronic components." Check that model's mantel-clearance chart before you commit to a TV location.
Can this be my main source of heat?
B-vent fireplaces send a large share of their heat up the flue, so they are chosen mainly for the look of the fire rather than as a heat source. If heating is the goal, a direct-vent model will do far more with the same gas.
What else do I need to buy to make this work?
A gas supply line run by a licensed gas fitter, plus a B-vent flue system sized for the unit and run vertically to the roof. Framing and finish materials are supplied by you or your builder.
