How to Install Fireplace Doors: A Comprehensive DIY Guide

Upgrading your Heatilator fireplace with new glass doors not only enhances its appearance but also improves safety and energy efficiency. In this DIY guide, we'll walk you through the steps to install your Heatilator fireplace doors, with expert tips from a fireplace door specialist.

Reasons to Upgrade Your Fireplace with New Doors

Fireplace doors provide an additional safety barrier, preventing pets and children from coming into contact with the open flames.

They also help to reduce heat loss, by acting as a barrier between your home and the chimney, preventing cold drafts from entering and warm air from escaping when the fireplace is not in use. This makes your fireplace more energy-efficient.

New doors also improve the look of your hearth, giving it a more polished and finished look.

About Our Fireplace Door Options

We only sell Heatilator fireplace doors specifically for Heatilator fireplaces. These bi-fold glass doors have been specifically tested for use with Hearth & Home Technologies fireplaces (Hearth & Home is the parent company of Heatilator).

Many websites will sell custom-made fireplace doors, that MIGHT be able to fit, but more often than not they don't fit correctly and are not specifically made to fit Heatilator fireplaces. 

Step-By-Step Heatilator Fireplace Door Installation Guide

  1. Fold one pair of doors. Insert the pin into the large hole located at the bottom outside corner of the fireplace opening.
  2. Tilt the doors toward the center of the fireplace, so the pins clear the top door track edge. Slide the pin into the top door track until the pin snaps into the hole in the spring clip.
  3. Doors may be adjusted by repositioning the spring clips in the screw slots, by loosening the screws and then retightening. Do not overtighten the screws!
  4. If removal becomes necessary, depress the spring clips located in the upper corners of the fireplace and tilt the doors towards the center of the fireplace opening.

Proper Operation of Bi-fold Glass Doors

  • Close the fire screen when burning the fireplace.
  • Do not use the fire screen or glass doors to hold burning material in the fireplace. Firescreen controls sparks, and glass may break, or burning material may roll out.
  • Doors must be fully opened or fully closed when operating the fireplace. Partially opened doors may draw flame, smoke, or heat from the fireplace.
  • Fully Open: Correct
  • Fully Closed: Correct
  • Partly Closed: Incorrect
  • Partly Open: Incorrect (pic)

Other Safety Precautions 

  • Wear protective gloves and safety glasses during installation to avoid injury from sharp edges.
  • Before burning the fireplace for the first time, wipe the trim with a clean, dry rag to remove all smudges and fingerprints. Failure to do so will cause smudges and fingerprints to be burned into the finish of the trim.


How Do I Determine My Fireplace Make and Model?

You can locate your fireplace model number and the date code on the interior plate of your fireplace. The date code typically consists of a 4-digit number, such as 6391.

Each Heatilator fireplace features a rating plate located either inside the operation door or in the lower control cavity. This plate displays your fireplace's model and serial numbers.

For wood-burning fireplaces, a metal serial/model plate can be found on the upper left or right side of the firebox, or riveted on the smoke shield behind the screen.

Gas-burning fireplaces and inserts have a serial/model/rating plate in the lower control cavity area.

What If I Don't Have a Heatilator Fireplace?

Because our doors will only fit Heatilator-brand fireplaces, the above installation instructions may not be appropriate for you. However, the below steps should help you install other standard size fireplace doors and custom-made fireplace doors.

Tools and Materials: What You Might Need for the Installation

  • Measuring tape
  • Electric drill with regular drill bits and masonry drill bits
  • Phillips head screwdriver
  • Socket wrench
  • Hammer
  • Level
  • Pliers
  • Hardware (included with fireplace doors)
  • Safety goggles

Measure the width, height, and depth of your fireplace opening, and record these measurements to ensure you purchase the correct model.

Installation Guide

  1. Remove the existing fireplace screen or doors if present.
  2. Unpack and inspect your new fireplace glass doors and the included hardware, such as lintel clamps, angle brackets, and sheet metal screws.

  4. Position the door frame in the fireplace opening, ensuring it is level and centered.
  5. For masonry fireplaces, mark the locations of the mounting holes on your fireplace wall using a pencil. For pre-fab fireplaces, locate the metal lintel bar and mark the screw holes on the lintel.
  6. Remove the door frame and drill holes at the marked locations using an electric drill with the appropriate drill bits (masonry drill bits for masonry fireplaces, regular drill bits for pre-fab fireplaces).
  7. Attach the door frame to the fireplace using the provided lintel clamps, sheet metal screws, or other hardware as specified by the fireplace manufacturer.
