6.4 Variable Heat Output Adjustment
1.
Some models of propane (LP) gas or natural gas heaters have a throttle valve located between the
gas control valve and gas manifold assemblies which is used for varying the heat output. THIS IS
NOT A MANUAL GAS CUT OFF VALVE.
2.
The throttle valve can be adjusted to deliver either minimum heat or maximum heat. When the
throttle valve handle is parallel to the gas flow, the valve is completely open to deliver maximum
heat output. Refer to
Figure 5
. The throttle valve may be adjusted to minimum heat output by
turning the handle 90° to the gas flow or any position between the maximum and minimum
settings. Refer to
Figure 6
.
