CONDENSATE DRAIN (Continued)
Have you confirmed the condensate drain line is not connected with an air conditioning
evaporator coil drain?
This boiler has an integrated condensate trap. Have you verified that an external
condensate trap is not installed?
Have you confirmed the end of the condensate drain pipe is open to atmosphere?
Has an air gap been installed in the condensate drain line?
PRESSURE RELIEF VALVE (PRV)
Does the PRV comply with the standard for Relief Valves and Automatic Gas Shutoff
Devices for Hot Water Supply Systems ANSI Z21.22, and/or the standard Temperature,
Pressure, Temperature and Pressure Relief Valves and Vacuum Relief Valves, CAN1-4.4?
Did you verify the DHW PRV is rated up to 150 psi and (at least) the maximum Btu/hr of
the boiler and the heating system PRV rated to 30 PSI?
Is the discharge from the PRV piped to the ground or into a drain system as per local
codes?
Is the discharge line from the PRV pitched downward and does it terminate 6 in. (152
mm) above the drains?
Is the discharge end of the line plain (unthreaded) and a minimum of 3/4 in. diameter?
Is the discharge line material suitable for at least 180° F water?
Did you take measures to protect the PRV and PRV discharge line from freezing?
Have you verified the PRV is not plumbed with the condensate drain line?
Have you verified the PRV is not plugged and that reducing fittings, valves, or other
restrictions are not installed in the relief line?
GAS SUPPLY
Did you verify the gas system is appropriately sized?
Did you verify the boiler is rated for the gas type supplied?
Have you performed a gas line and connection leak test?
Did you install a manual gas control valve in the gas line to the boiler?
When the boiler is in operation, is the inlet gas pressure within limits?
Did you purge the gas line of any debris before connecting the boiler?
POWER SUPPLY
Did you confirm that the electricity is supplied from 120 VAC, 60 Hz power source and is
in a properly grounded circuit?
Did you confirm that an extension cord or an adapter plug has NOT been used with the
boiler?
COMMISSIONING
Did you prime the pump?
Was the boiler filled to 17-26 PSI?
Was the air purge process performed on the boiler?
