1.8 INSTALLER TESTING
The space heater must be tested and be operating ac- cording to manufacturers specifications prior to the in- staller leaving the site. Note: the tips of the flames should never hit the top of the firebox after the unit has warmed up. Please contact your dealer or a qualified service person to replace injector or adjust valve.
Upon completing the gas line connection, a small amount of air will be in the lines. When first lighting the pilot light, it will take a few minutes for the lines to purge themselves of this air. Once the purging is com- plete, the pilot and burner will light and operate as indi- cated in the Lighting Instructions.
Subsequent lightings of the appliance will not require such purging.
CAUTION: DURING THE INITIAL PURGING AND SUBSEQUENT LIGHTINGS, NEVER ALLOW THE GAS VALVE CONTROL KNOB TO REMAIN DE- PRESSED IN THE "PILOT" POSITION WITHOUT PUSHING THE RED IGNITOR BUTTON AT LEAST ONCE EVERY SECOND.
Follow the Safety Information and Lighting Instructions pages of this manual to light the appliance.
To obtain proper operation, it is imperative that the pilot and main burner flame characteristics are steady, not lifting or floating. Typically, the top

2.0 OPERATING INSTRUCTIONS
This appliance is a balanced flue heater and is designed to operate with all combustion air being siphoned from the outside of the building and all exhaust gases ex- pelled to the outside of the building.
!WARNING: THIS UNIT IS NOT FOR USE WITH SOLID FUEL.
The control system for these models is a millivolt type. It consists of a gas control valve/variable regulator, a standing pilot assembly, a thermopile/thermocouple assembly, a piezo ignitor, an ON/OFF rocker switch, and a safety high temperature limit switch. The con- trols are located in the lower compartment behind the lower grille. Access to this compartment is gained by rotating the grille up. See Figure 1.
!WARNING: DO NOT CONNECT
VAC TO THE GAS CONTROL VALVE OR CONTROL WIRING SYSTEM OF THIS UNIT.
The gas control system is wired so the thermopile, when heated with the pilot light, will provide approximately 350 to 500 millivolts. This activates the gas control valve. See Figure 28 for appliance wiring diagram.
When lit for the first time, the appliance will emit a slight odor for an hour or two. This is due to paint and lubri- cants used in the manufacturing process. Additionally, for the first few minutes after each lighting, vapor may condense and fog the glass and the flames may be blue. After a few minutes this moisture will disappear and within
The heater may produce a noise, caused from metal expansion and contraction as it heats up and cools down. This noise is similar to one that a furnace or heat duct may produce and does not affect the operation or longevity of the heater.
