Failure to follow the instructions in this section WILL VOID the
warranty and may result in property damage, severe personal
injury, or death.
Dielectric unions or galvanized steel fittings must not be used in a
system with this boiler. Doing so WILL VOID the warranty. Use only
copper, brass, or stainless steel fittings. Teflon thread sealant must
be used on all connections.
The National Standard Plumbing Code, the National Plumbing
Code of Canada, and the Uniform Plumbing Code limit heat
transfer fluid pressure to less than the minimum working pressure
of the potable water system up to 30 PSI maximum. In addition,
the heat transfer fluid must be water or another non-toxic fluid
having a toxicity of Class 1, as listed in Clinical Toxicology of
Commercial Products, 5th Edition. Failure to follow this warning
could result in property damage, severe personal injury, or death.
Plumbing of this product should only be done by a qualified, licensed
plumber in accordance with all local plumbing codes. The boiler
may be connected to an indirect water heater to supply domestic
hot water. HTP offers indirect water heaters in a wide range of gallon
sizes in either stainless steel or glass-lined construction.
A. General Plumbing Information
Use two wrenches when tightening water piping at boiler. Use one
wrench to prevent the boiler return or supply line from turning.
Failure to prevent piping connections from turning could cause
damage to boiler components.
The building piping system must meet or exceed the the piping
requirements in this manual.
The control module uses temperature sensors to provide both high
limit protection and modulating temperature control. The control
module may also provide low water protection (through the addition
of an optional kit) by sensing the water level in the heat exchanger.
An optional flow switch may be installed on the supply of the system
to activate the boiler when there is enough flow. Some codes/
jurisdictions may require additional external controls.
NOTE:
The addition of a high temperature limiting device is important
if the boiler is to be connected to a domestic hot water system.
