The gas knockout is determined by an indentation located at the bottom and slightly off center in the side refractories. THE KNOCKOUT IS ALWAYS REMOVED FROM INSIDE THE FIREBOX. If removal is attempted from the outer wrapper, side-refractory damage may occur. With a medium-sized hammer, lightly tap the surface of the indentation. The refractory material is very thin in this area and is easily removed. Once a small hole has been made, continue tapping until you have reached sufficient diameter for the gas line to fit through. The entire knockout does not have to be removed. Install only a ..." (1 ..." max.) inside diameter approved gas line through the firebox wall for connection to the unvented room heater inside the firebox. Ensure that a sediment trap is installed in the existing gas line, if not, install a sediment trap upstream of the heater to prevent moisture and contaminants from passing through trap to the heater controls and burners. Failure to do so could prevent the heater from operating reliably. An external regulator must be used on all propane (L.P.G.) heaters, in addition to the regulator fitted to the heater, to reduce the supply tank pressure to 13" w.c. (maximum). Any copper tubing used to supply propane (L.P.G.) from the tank must be internally tinned. IMPORTANT: HOLD HEATER REGULATOR WITH A WRENCH TO PREVENT MOVEMENT WHEN CONNECTING TO INLET PIPING. Check Gas Type: The gas supply must be the same as stated on the heater’s rating plate. If the gas supply is different, DO NOT INSTALL the heater. Contact your dealer for the correct model. WARNING: CONNECTING DIRECTLY TO AN UNREGULATED PROPANE (L.P.G.) TANK CAN CAUSE AN EXPLOSION. IMPORTANT: RE-PACK INSULATION MATERIAL IN SQUARE HOLE AROUND GAS LINE, INTERIOR AND EXTERIOR, TO SEAL. Consult installation and operating instructions for the model of unvented room heater to be installed. Checking Gas Connections: Test all gas joints from the gas meter to the gas heater regulator for leaks using soap and water solution after completing connection. DO NOT USE AN OPEN FLAME. NOTE: DIAGRAMS & ILLUSTRATION NOT TO SCALE. Firebox Framing Firebox Framing The firebox may be installed directly on a combustible floor or raised on a platform of an appropriate height. Do not place firebox on carpeting, vinyl or other soft floor coverings. It may, however, be placed on flat wood, plywood, particle board, metal or other hard surfaces which extend the full width and depth of the enclosure. Be sure firebox rests on a solid continuous floor or platform with appropriate framing for support and so that no cold air can enter room from under the firebox. The firebox may be positioned and then the framing built around it, or the framing may be constructed and the firebox positioned into the opening. Usually, no special floor support is needed for the firebox, however, to be certain: 1. Estimate the total weight of the firebox system and surround materials such as marble, brick, stone, etc., to be installed. 2...
