17.0 GAS PRESSURE CHECK

The heater regulator controls the burner pressure which should be
checked at the pressure test point located on the appliance inlet pipe .
The appliance inlet pipe runs between the regulator and the gas valve
and the test point is located next to the regulator as shown in Figure 7a .
Turn off the gas supply before removing the pressure
test point screw.
The test point is situated before the appliance gas valve so it will be
necessary to turn off the gas supply before removing the test point
screw . Connect the pressure gauge .
Figure 7a - Remove test point screw
Turn on the gas supply and light the heater . Turn the control to the high
flame setting and check the pressure . The pressure regulator on manual
models is preset and locked to avoid tampering . If the pressure is not as
specified in Table 1 on Page 7, replace the regulator with P/N H6063
for Natural Gas units and H7001 for Propane Gas units . Replace the test
point screw ensuring no gas leaks .

SPARK GAP

The gap between the spark electrode and the pilot should be 1/8" to
3/16" to produce a good spark . There should be no need to adjust this
(DO NOT ATTEMPT TO ADJUST THE GAP) . If under any circumstances
the piezo electric spark fails, the pilot cannot be lit manually .
Adjustment to the
1/8" to 3/16" Spark Gap
pilot is Not allowed
