Fireplace Dimensions

Please follow the instruction below to measure your fireplace.

To make a recommendation we need to know:

---Width at the opening?

---Width at back?

---Height at the opening?

---Depth at bottom?

---Depth at top?

If ordering a Q we need to know:

---the outside width of your door frame?

Make sure to measure behind any screen or door in use.

Our products use a model number that relates to the items dimensions. First # is product width. second is tall/deep (Models that don't have a tall are 6" tall)

select the model that is equal to or smaller than your measurements. NOTE 3" adjustable legs not included in height and can add whatever height you adjust them to.

We have Several different styles to chose from, this is indicated by the letter code in the model number:

(GR) Our Standard fireplace heat exchanger. Sturdy and effective. 5"X3" rectangular steel 1/8" thick for the manifold and 16 gage 1" tubing for the grate.

(GR -F) Same as GR but no manifold or fan, for those who want an absolute silent operation. These fanless models operate on natural convection!

(TGR) Same as the GR with the back tapered down 1 size level. (24 wide front = 20 wide back)(14 wide front = 12 wide back)(36wide front =30 wide back) Ect.

(TGR -F) Same as TGR but also no manifold or fan. Operating on natural convection!

(DGR) Once again same as GR. This time with twice as many tubes and an extra fan for blowing power. for those who have a large space to heat and really want to crank up the flow.

(RC) Our solution for a double sided fireplace. The Rib Cage will draw air in from one side then blow it out the other, all the while allowing a clear view through the center of your double sided fireplace. Allowing for a great view of the fire.

(Q) Here we switch to our 5"X2" rectangular steel 1/8" thick steel. the Cubes are a standardized option to use our heat exchanger with your existing glass doors closed. the Q is the First base line option (existing fireplace doors need to be removed to install the Cubes then re installed on top of the 2" manifold that the fan and exhaust attach to.)

(QQ) Second in the Cube line is the QQ. Adds a vertical dimension for added heat transfer

(QQQ) And Third in the Cube line is the QQQ. Has Surface area directly over the flames for maximum heat transfer and the most tube distance for the heat to transfer. The QQQ also comes with the Fireback standard!

(HTH) Our most economical option available the Hard Times Heater is based off the Q without the support for the doors. available with the fan built on the left or the right.

(DS) Same as the HTH but designed to work with double sided fireplaces. again available in left or right.
