C. Reading Pressures
1. With the heater operating, the pressure gauges should read
the pressures specified on the dataplate.
2. Do the readings at the inlet and outlet pressure gauges
agree with that specified on the dataplate? If so, then no
further checking or adjustment is required. Proceed to
section D.
3. If the inlet pressures do not agree with that specified on the
dataplate, then the regulator controlling gas pressure to the
heater requires adjustment.
4. If the inlet pressure is correct but the burner manifold
pressure does not agree with that specified on the dataplate,
then the gas control valve's internal pressure regulator
needs adjustment:
-- Remove the regulator cap on the control valve.
-- Using a standard screwdriver turn the adjusting screw
clockwise (to increase pressure) or counter-clockwise (to
decrease pressure) until the burner manifold pressure is set.
-- Install regulator cap.
-- Proceed to COMPLETION.

C. Completion
1. Once the proper inlet and burner manifold
pressures have been confirmed and/or properly
set, close the fuel supply valve to the heater and
allow the heater to burn off any gas remaining in
the gas supply line.
2. Disconnect the heater from its electrical supply and
close fuel supply valve.
3. Remove the gauges.
4. Install pressure tap plugs.
5. Open fuel supply valve and reconnect electrical
supply to heater. Start the heater and check for
gas leaks.
6. Set thermostat to desired temperature.
