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. See Figure 24. Please contact your dealer
or a qualified service person to replace injector or ad-
just 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.
FIGURE 24
To obtain proper operation, it is imperative that the pi-
lot and main burner flame characteristics are steady,
not lifting or floating. Typically, the top 3/8-inch (9.5mm)
at the pilot generator should be engulfed in the pilot
flame. (Figure 25.)
Burner flame patterns are shown in Figure 26.
Follow Section 3.5 TROUBLESHOOTING for adjusting
the appliance to operate properly.
