12. STARTUP
WARNING:
These startup instructions are prepared for a qualified service installer, service agency or
gas supplier and require and rely on the experience and training of these qualified gas appliance
technicians to be safely completed. Attempting to follow these instructions without such training and
experience can result in property damage, exposure to hazardous materials, personal injury or death.
WARNING:
High Voltage Shock Potential - Turn off all electrical service to the appliance when accessing
the gas valve, condensate trap, blower, hot surface ignitor and other components located inside the
lower front and rear panels. After access, close and fasten the lower front and rear panel covers before
restoring electrical service to the appliance. Wires and terminals, such as the gas valve terminals carry
High Voltage (120V). If the electrical service is not turned off, or if the covers are not replaced, and these
terminals are touched, a dangerous shock causing personal injury or loss of life could occur.
1. Remove lower front jacket cover to expose the burner and gas train assembly.
2. Visually check that all components are intact and no damage has occurred during transit or installation.
3. Check all connections within the control cabinet. A loose wire connection could cause intermittent
shutdowns.
4. Check the inlet/supply gas pressure before startup, using a U-tube manometer or a 0 to 28" W.C. pressure
gauge for inlet gas pressure (This is the pressure measured before all components in the gas train). The
manometer must stay connected throughout the testing to monitor the inlet gas pressure while the burner is
firing. Record static pressure when not firing and record flow pressure while firing and ensure these
pressures do not exceed the maximum inlet pressure and is not below the minimum inlet pressure shown on
the appliance rating plate located on the front control panel door. Pressures above or below those on the
rating plate could result in gas valve damage, unreliable operation or the creation of dangerous carbon
monoxide.
5. Check the flue gases with an electronic combustion analyzer to make final adjustments to the gas pressure
regulator:
a. Readings should be taken through a small hole in the vent located no more than 12 inches downstream
of the appliance flue outlet.
b. Measure the vent pressure using a manometer or draft gauge capable of reading up to 1/2" W.C. and
record vent pressure. Vent pressure must not 0.4" W.C., Excessive vent pressure indicates a
vent obstruction or inadequately sized vent.
c. When water in tank is above 120°F, insert the analyzer sensor into the hole in the vent and record O
2
reading (4% to 7.5%). Record CO
2
if available.
d. Record CO reading (200 ppm maximum).
e. To prevent products of combustion from escaping, cover the test hole in the vent with aluminum
adhesive tape.
f. Check the operating control to be sure it functions properly by lowering and raising the operating
temperature setting (see section “Thermostat Setting”) causing the burner to cycle on and off.
Important: Contact PVI Customer Service if any recommended setpoint or analysis reading falls outside
of the recommended ranges before completing startup.
