MEASURING YOUR FIREPLACE OPENING:
Glass Doors: See the chart that follows for recording your measurements!
 Measure the face of the opening height on both sides and width at top and bottom.
There is no standard when it comes to masonry and the opening may not be square
so it is important to be thorough.
 Many doors mount to the lintel bar with a sliding clamp system, so look in the roof of
your opening for a metal bar, which supports the weight of the bricks during
construction. Measure how far back the lintel bar sits from the face of the opening
and it’s total depth/thickness.
 A damper control handle may protrude from the face of your fireplace. It is
important to record its distance and position from the opening when sizing a glass
door.
 Take additional measurements showing any decorative tile or stone and clearances
to mantels and surrounds.
 Note if there is a raised hearth. (Floor or fireplace is raised above floor of room.)
 The more information we start with, the easier it is to properly fit and proportion a
glass door to your fireplace. Now, just bring your diagram to the store and be
amazed at the selection of styles and colors you have to choose from!
Gas Logs: For correct sizing of a gas log set we will need to have all of the above
measurements, as it is important to have a glass door installed with the logs’ standing pilot
system. (Note: glass doors are opened while gas logs are burning).
 For the log size measure the floor of the firebox width and depth.
 Note the size of the flue; there is a minimum size requirement to ensure the proper
draft of exhaust fumes up the chimney.
Stove Inserts: Both wood and gas inserts will need to fit inside the opening and then have
trim panels to cover the gap between the stove and the fireplace opening.
 Complete the diagram in full, noting all of the dimensions on the face (per glass
door instructions).
 Measure the depth of the floor of the firebox (face to back wall).
 Measure the slanted ceiling if any. The height of the back wall before the slant and
the length of the ceiling depth before it begins to slant down.
 WOW, that’s a lot! That’s why we inspect and re-measure every job as part of our
final quote, so there are no surprises for you or our installers!
Zero-Clearance Fireplaces: You may be starting with a blank wall or corner but there are
some important considerations.
 How much space do you have between windows?
 What is outside in terms of plantings or walkways?
 What would you like in terms of tile or marble surrounds and wooden mantels or
cabinets?
 How much space will you be heating?
