FRAMING
Once the final location has been determined, observing height clearances for vent termi- nation, you may construct framing using dimensions shown in Figure 6, depending on your installation.
If the appliance is to be installed directly on carpeting, tile (other than ceramic), or any combustible material other than wood floor- ing, the appliance must be installed on a metal or wood panel extending the full width and depth of the appliance. There are three holes on each side of the bottom of the unit where screws can be used to secure the unit to the floor.

following guidelines:
•Only use Vanguard or Simpson Dura- Vent GS venting components or kits spe- cifically approved for this fireplace.
•Minimum clearance between vent pipes and combustible materials is 1" (25 mm), except where stated otherwise.
•Combustible material may be flush with the top front of fireplace with a maxi- mum thickness of 3/4".
•Do not recess venting terminals into a wall or siding.
•Install horizontal venting with a 1/4" rise for every 12" of run toward the termination.
•You may paint the vent terminal with 450°F (232°C)
•There must not be any obstruction such as bushes, garden sheds, fences, decks, or utility buildings within 24" from the front of the termination cap.
•Do not locate termination cap where exces- sive snow or ice build up may occur. Be sure to clear vent termination area after snow falls to prevent accidental blockage of venting system. When using snow blowers, do not direct snow towards vent termination area.
