INTRODUCTION Models GL36PN/P and GL36PNE/P are decorative gas appliances that use a millivolt gas control and piezo pilot or an electronic gas control valve with an electronic ignition system respectively. These systems require a 6", B-type venting system for operation. The 6" B-type vent is not supplied by DESA. For installation guidelines, check your B-vent instructions. WARNING: This gas appliance must not be connected to a chimney flue servicing a solid fuel burning appliance.
SELECTING LOCATION 1" Minimum Clearance to Combustibles Continued In selecting a location, the following precautions must be observed: 1. Do not connect this appliance to a chimney system used for a solid fuel burning fireplace. 2. Install in an area providing ventilation and adequate combustion air. 3. Due to high temperatures, do not locate this appliance in high traffic areas or near furniture and draperies. 4.
FIREPLACE INSTALLATION 1" Min. to Combustibles Continued Nailing Flanges FRAMING Construct framing using dimensions shown if Figures 6, 7 and 8. (Use the figure applicable to your application.) Figure 6 shows the framing dimensions prior to having the appliance in place. If installing on a platform, platform must be solid, flat and fully supported (see Figure 7).
The installation of an outside air kit should be completed during the rough framing of the fireplace due to the nature of it's location. Outside combustion air is accessed through a vented crawl space. CAUTION: Air inlet ducts must not be terminated in an attic space. Avoid installing outside air eyebrow in areas where inlet opening may be blocked by snow, bushes or other obstacles (see Figure 10).
FIREPLACE INSTALLATION The gas control valve is secured to the burner pan assembly underneath the front ledge. A 1/8" NPT plugged tapping is provided on the gas control valve for a test gauge connection immediately upstream of the gas supply connection to the appliance (see Figures 13 and 14).
FIREPLACE INSTALLATION Shutoff Valve Key Continued To install: 1. Remove gas line cover plate from applianceʼs outer surround at the location to be used. 2.
