Post-Start Check List
After the entire control circuit has been energized and the
heating section is operating, make the following checks:
1. Check for gas leaks, using soapy solution, in the unit
piping as well as the supply piping.
2. Check for correct manifold gas pressures (see Manifold
Gas Pressure Adjustment Regulator sections).
3. Check the supply gas pressure. It must be within the
limits shown on the rating plate. Supply pressure should
be checked with all gas appliances in the building at full
fire. At no time should the standby gas pressure exceed
13" w.c., nor the operation pressure drop below 5" w.c.
for natural gas units or 11" w.c. for propane gas. If gas
pressure is outside these limits, contact the gas supplier
for corrective action.
4. Adjust temperature rise to the range specified on the
rating plate.
