RULES FOR SAFE INSTALLATION AND OPERATION
! !
• Frequent and mysterious lifting of the relief valve
may be a sign of an improperly sized expansion
tank. Installation and sizing of the expansion tank
must consider the heating system’s total water
volume, temperature, boiler initial fill pressure, and
system arrangement. For proper installation and
maintenance follow the guidelines established by
ECR and the manufacturer.
• Expansion tank performance and life expectancy
can be hindered by overfilling the boiler. ECR
recommends an initial fill pressure of 10 – 12 psig.
For higher fill pressures, the expansion tank’s
air charge will need to match the fill pressure.
Consult the manufacturer’s guidelines for sizing
and selection.
• Purging the heating system of air and gases during
the boiler’s initial commissioning is critical for proper
circulation and quiet performance. Once the air
and gases are purged, for boiler installations using
float type vents, the air vents should be closed for
normal operation. If air is heard or noticed by a
loss of heat, purge the system and open the vents
for a short period of time.
CAUTION
This boiler has been designed for residential
installations. If used for commercial applications,
all jurisdictional requirements must be met. This
may require wiring and/or piping modifications.
The manufacturer is not responsible for any
changes to the original design.
DO NOT USE GASOLINE CRANKCASE
DRAININGS OR ANY OIL CONTAINING
GASOLINE.

BEFORE YOU START
Check to be sure you have the right size boiler
before starting the installation. See rating and
capacity tables on preceding pages. Check the
rating plate on the right side of the boiler.
You must see that the boiler is supplied with the
proper fuel, fresh air for combustion, and a suitable
electrical supply. Also, the boiler must be connected
to a suitable venting system and an adequate piping
system. Finally, a thermostat, properly located, is
needed for control of the heating system. If you
have any doubts as to the various requirements,
check with local authorities and obtain professional
help where needed.
These installation instructions are vital to the proper
and safe operation of the heating system. Take the
time to be sure they are carefully followed.
CAUTION
Always keep the manual fuel supply valve shut
off, if the burner is shut down for an extended
period of time.
