Gas direct vent fireplaces are popular fireplaces that burn efficiently enough to be a heat source but not too efficient to where the fire lacks realism. They can be vented both vertically or horizontally. Their fireboxes exhausts the inner vent pipe while drawing outside air for combustion through the outer pipe.

NOTE: The Gas Saving Pilotless Electronic Ignition - Propane Gas option, previously known as B36PTRE has been updated to B36PTREA-1

Questions and Answers

Customer Questions
How do I remove the front of this unit to clean the glass?
Before the glass door can be removed, the safety barrier must be removed. Lift the safety barrier off the 4 pins, tilt the top forward, and remove from the appliance. Leave a hand on the glass door during the entire door removal. The glass door is secured to the firebox with 2 spring latches along the top and 2 along the bottom. Pull the handles of the latches forward, then lift the latches out from the door frame to release the top of the door. Repeat the same step for the 2 bottom latches. Next, pivot the door forward until the top edge clears the front of the appliance. Carefully grip the sides of the door, lifting it off the appliance. NOTE: The spring latches constitute the spring relief system for the appliance. Ensure they are open freely and close with a tight seal. Reverse these steps to reinstall the safety barrier and door. Ensure safety barrier is installed correctly. If you have any further questions please feel free to give us a call! Thanks.
