QVM 9
Series 28
1) Check the flammability and rigidity of floor &
wall materials. Ensure that all minimum
clearances to walls, ceilings, overhangs, etc.
have been met.
2) Freeze Prevention Device
The units must be wired-in to a 115 volt
electrical circuit once they have been connected
to water piping and the circuit has been filled with
water. If the freeze prevention circuit starts due to
a low-water condition, the pump will begin running
on “air” and cause premature failure and will void
the warranty on the pump.
Check to see if the unit is properly connected
and the piping is insulated properly.
If the insulation has worn off or is not fitted, the
risk of freezing of piping and severe damage to
the unit is considerable. Thoroughly check the
piping insulation and replace where necessary.
■ Measures to prevent fire must be taken and
check that flue ducts are installed in compliance
with the instructions?
■ Are there any water leaks in the heating and
domestic hot water piping?
■ Are there any gas leaks in the gas piping?
■ Type of gas being supplied(the one indicated on
the rating plate of the units)
■ When the type of gas does not match the one
specified on the unit rating plate, modification and
re-adjusting will be required(Consult your heating
dealer or a qualified technician with the gas utility
company).
■ Test for leaks at all gas piping connections.
■ AC 115 volts 15 Amp. dedicated circuit with approved
grounded connection.
■ Heating and hot water pipes must be properly
installed and in compliance with the standard
installation methods and local code requirements.
CAUTION ! Any air remaining in the heat exchanger
piping will cause rapid corrosion in the unit.
■ Completely vent the air at this time.
■ Check DIP switch setting against the factory
settings shown on the control board diagram.
■ Check for proper flue pitch, slope and alignment
for QVM 9(condensing) hydronic heating systems.
■ Fill plastic condensate trap in QVM 9 check correct
routing of all condensate and vent drain tubing. Run
condensate drain by gravity to nearest floor drain
or condensate pump. Note ! - Condensed water is
slightly acidic. Avoid draining into piping in disrepair
or piping exposed to freezing temperatures.
■ Connect room thermostat and check all wiring
connections at control, at molex connectors in unit
and at main circuit panel.
