Installation
3.1
Receiving The Boiler
The boiler is shipped from the factory with
(4) shipping feet/legs bolted to the skids.
These are provided to facilitate unloading
/moving with a forklift. Lifting points are
also provided to enable over-head lifting with
spreader bars to prevent damage to the boiler.
The shipping feet/legs MUST BE
REMOVED after the boiler is set in-place on
its concrete foundation before any
piping/electrical connections are made. It is
recommended that the plastic protective
cover be left on as long as possible to reduce
finish damage from the installation.
3.2
Boiler Connections
Do not run any pipes along the tube access
panel side of the boiler. Maintain clearances
as shown on the dimensional drawing for
servicing of the boiler tubes. All piping
should be designed and installed to avoid any
loadings on the boiler connections or piping.
3.2.1
Flow Connection
The system supply and return flow
connections are shown on Figure 1. A gate
valve should be installed on the boiler outlet
and inlet lines. This allows the boiler to be
isolated from the heating system for draining
and servicing.
3.2.2
Safety Relief Valves
Safety relief valve(s) are shipped loose.
Connections are provided in the top of the
boiler for the safety relief valve(s). The safety
relief valve discharge piping must be the same
size as the safety relief valve discharge
opening and run to a point of safe discharge.
No shutoff valves are to be placed between
the relief valve and the appliance or in the
discharge piping. Avoid over-tightening as
this can distort valve seats. All piping from
the safety relief valve(s) must be
independently supported with no weight
carried by the valve.
NOTICE
If the relief valve discharges periodically,
this may be due to thermal expansion in a
closed water supply system. Contact the
water supplier or local plumbing inspector
on how to correct this situation. DO NOT
PLUG THIS RELIEF VALVE.
3.2.3
Expansion Tank Connections
Connection(s) to an expansion tank are to be
provided by others in the system piping
separate from the boiler.
3.2.4
Drain Connection
A drain valve must be installed on the boiler
drain connection, the same pipe size as this
connection, to allow draining of the boiler.
3.2.5
Condensate Drain Connection
A condensate drain trap is shipped with the
boiler and is provided with a 1” nps
connection to drain the condensed products
of combustion from the boiler. Pipe with
continuous Teflon, high temperature silicone
tubing, or other tubing material compatible
with flue gas condensate. The condensate
temperature should never exceed 212
o
F and
the pH of the condensate should never have a
value lower than 3.5. NO VALVE is to be
