GENERAL INSTALLATION INFORMATION Counter Cast Iron Stove ON OFF H L2 L1 W Figure 3 - Example of a Large Room with 1/2 Wall Divider The following formula can be used to determine the maximum heater rating per the definition of unconfined space: BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft x 1000 50 Consider two connecting rooms with an open area between, with the following dimensions: L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.
WARNING CLEARANCES / HEIGHT REQUIREMENTS The dimensions shown in Figure 4 are minimum clearances to maintain in installing this heater. Left and right clearances are determined when facing the front of the heater. Follow these instructions carefully to ensure safe installation. Failure to follow instructions exactly can create a fire hazard.

Internally tinned copper or copper tubing can be used per National Fuel Code, section 2.6.3, providing gas meets hydrogen sulfide limits, and where permitted by local codes. Gas piping system must be sized to provide minimum inlet pressure (Listed on Data Plate) at the maximum flow rate (BTU/Hr).
The heater gas inlet connection is 3/8" NPT at the valve. The inlet is located on left side of stove. Remove front control plate to better access the inlet. When tightening up the joint to the valve, hold the valve securely with a wrench to prevent movement. WARNING CHECKING GAS PRESSURE AND CONNECTING REMOTE RECEIVER Connecting directly to an unregulated propane/L.P.G. tank can cause an explosion.
ELECTRICAL WIRING (MILLI-VOLT) The milli-volt valve is a self-powered combination gas control THAT DOES NOT REQUIRE 110 VAC TO OPERATE. CAUTION ODS Pilot Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.
ELECTRICAL WIRING (MILLI-VOLT) 4. Remove adhesive backing from plastic clip. Press clip to bottom of valve. Clip thermo bulb into plastic clip. See Figure 13. 5. Reattach faceplate or reinstall base. 6. Install knob to shaft of t-stat sensor. See Figure 13, page 17. Valve Thermo Bulb Plastic Clip Figure 13 - Clipping Thermo Bulb into Plastic Clip. OPERATING THERMOSTAT SENSOR 1. Follow millivolt lighting instructions on lighting plate attached to unit or in homeownerʼs manual. 2.
LOG PLACEMENT WARNING Before you begin — This unit is supplied with four ceramic fiber logs. Do not handle these logs with your bare hands. Always wear gloves to prevent skin irritation from ceramic fibers. After handling the logs, wash your hands gently with soap and water to remove any traces of fibers. The positioning of the logs are critical to the safe and clean operation of this heater. Sooting and other problems may result if the logs are not properly and firmly positioned in the appliance.
ROCK WOOL INSTALLATION ➞ 1. Break rock wool into dime-sized pieces. 2. Place rock evenly across rock wool tray and front burner as shown in Figure 18. • Rock wool depth must not be more than 1". • Do not place rock wool past the bend in rock wool tray. WARNING • Do not place rock wool on rear burner. Bend in Rock Wool Tray Rock wool must be placed correctly. Placing rock wool in wrong area will create high carbon monoxide.
FLAME APPEARANCE CHECKING BURNER FLAME In normal operation at full rate after 15 minutes, the following flame appearances should be observed: The left and right rear flames should be yellow and extend 1"-2" above middle logs. The yellow flames should not contact the logs. There should be glowing embers on the front surface of the middle log. Note: The flames and embers will be an opaque orange color during the burn off time.
