WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS Water vapor is a by-product of gas combustion. An unvented room heater produces approximately one (1) ounce (30 mL) of water for every 1,000 BTUs (0.3 KWs) of gas input per hour. Unvented room heaters are recommended as supplemental heat (a room) rather than a primary heat source (an entire house). In most supplemental heat applications, the water vapor does not create a problem.
AIR FOR COMBUSTION AND VENTILATION VENTILATION AIR Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12" of the ceiling and one within 12" of the floor on the wall connecting the two spaces (see options 1 and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2). Follow the National Fuel Gas Code, ANSI Z223.
INSTALLATION NOTICE: This heater is intended for use as supplemental heat. Use this heater along with your primary heating system. Do not install this heater as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using heater. This will help circulate the heat throughout the house. In the event of a power outage, you can use this heater as your primary heat source. WARNING: A qualified service person must install heater. Follow all local codes.
INSTALLATION GAS SELECTION This appliance is factory preset for propane/LP gas. No changes are required for connecting to propane/LP. Only a qualified installer or service technician can perform gas selection and connecting to gas supply. Insert Gas Fitting for Propane/LP Gas Insert Gas Fitting for Natural Gas CAUTION: Two gas line installations at the same time are prohibited.
INSTALLATION 2. Apply thread sealant to the threads on the connection fitting. While pushing in, rotate the fitting clockwise until the threads engage the regulator. After the fitting has been hand tightened into the regulator use a wrench to complete tightening of the fitting. Install additional fitting to connect to the house supply. Use only the cap supplied on the regulator. Do not use an off the shelf pipe plug. This can damage the plunger.
INSTALLATION CLEARANCES TO COMBUSTIBLES WARNING: You must maintain the minimum clearances. If possible, provide greater clearances from floor, ceiling, and adjoining wall. Measure from outermost point of heater. Note: This firebox can not be installed in an existing fireplace. Install this firebox only in a ProCom Heating, Inc. mantel accessory approved for this product. Minimum Clearances For Side Combustible Material, Side Wall and Ceiling A.
INSTALLATION IMPORTANT: When finishing your firebox, combustible materials such as wall board, gypsum board, sheet rock, drywall, plywood, etc, must have 1/2" clearance to the sides and top of the firebox. Combustible materials should never overlap the firebox front. 29" 1. Frame in rough opening. Use dimensions shown in Figure 7 for the rough opening. If installing in a corner, use dimensions shown in Figure 9, for the rough opening. The height is 23 1/4", which is the same as the wall opening above. 2.
INSTALLATION CONNECTING TO GAS SUPPLY WARNING: A qualified service technician must connect heater to gas supply. Follow all local codes. WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator. WARNING: Do not overtighten gas connections. WARNING: For natural gas, Never connect heater to private (non-utility) gas wells. This gas is commonly known as wellhead gas. CAUTION: For propane/ LP gas, never connect heater directly to the gas supply.
INSTALLATION Typical Inlet Pipe Diameters Use 3/8" black iron pipe or greater. Installation must include an equipment shutoff valve, union, and plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 11). IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance. For propane/LP installations, apply pipe joint sealant lightly to male threads.
INSTALLATION CHECKING GAS CONNECTIONS WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once. WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. If bubbles form, there is a leak. Correct all leaks at once.

OPERATION FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. B. BEFORE LIGHTING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.
OPERATION 8. With control knob pressed in, push down and release ignitor button. This will light pilot. The pilot is attached to the rear of the burner. If needed, keep pressing ignitor button until pilot lights. Note: If pilot does not stay lit, refer to Troubleshooting, pages 26 though 29. Also contact a qualified service technician or gas supplier for repairs. Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure. 9.
OPERATION REMOTE CONTROL SYSTEM Programming the Remote and Receiver The remote and receiver must be “learned” to one another. To prepare the receiver box for learning, use a pen or small screwdriver to gently press and hold the learn button until you hear 3 series of beeps. 1. Place the slide switch on the receiver in the remote position (see Figure 24). 2. Turn control knob on the heater to the ON position. 3.
OPERATION Setting°F/°C Scale The factory setting for temperature is °F. To change this setting to °C, press the ON key and the OFF key on the remote control at the same time (see Figure 24, page 20). This will change from °F to °C. Follow this same procedure to change from °C back to °F. Manual Function To operate the system in the manual “MODE” do the following. ON OPERATION Press the ON key and the appliance flame will come on. During this time the LCD screen will show ON (see Figure 26).
INSPECTING BURNERS IMPORTANT: Owner’s should check pilot flame pattern and burner flame pattern often. Incorrect flame patterns indicate the need for cleaning (see Care and Maintenance, page 24) or service. WARNING: Only a qualified service person should service and repair heater. This includes maintenance requiring replacement or alteration of components. PILOT FLAME PATTERN Figure 28 shows a correct pilot flame pattern. Figure 29 shows an incorrect pilot flame pattern.
CARE AND MAINTENANCE WARNING: Turn off heater and let cool before servicing. CAUTION: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service technician. Heater may need more frequent cleaning due to excessive lint from carpeting, bedding material, pet hair, etc. WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
CARE AND MAINTENANCE ODS/PILOT CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/ pilot unit. Use a vacuum cleaner, pressurized air, or a small, soft bristled brush to clean. A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about 2" from where the pilot flame comes out of the pilot assembly (see Figure 33). With the unit off, lightly blow air through the air inlet hole.
