H. UNCRATING THE BOILER
UNCRATING BOILER
– Any claims for damage or shortage in shipment must be filed immediately against the transportation company
by the consignee.
Cold weather handling
– If boiler has been stored in a very cold location (below 0
o
F) before installation, handle with care until the plastic
components come to room temperature.
Remove all sides of the shipping crate to allow the boiler to be lifted into its installation location. The boiler is also equipped with leveling
feet that can be used to level the boiler properly on an uneven location surface. If surface flooring is rough, take care when sliding boiler
into position, as you could catch the leveling feet and damage the boiler.
PART 4 – BOILER PIPING
Failure to follow the instructions in this section WILL VOID the warranty and may result in property damage, serious injury, or death.
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, 5
th
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 PIPING INFORMATION
The building piping system must meet or exceed the piping requirements in this manual.
Use two wrenches when tightening water piping at the 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 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.
B. RELIEF VALVE
Connect discharge piping to a safe disposal location following the guidelines in the following statement.
Never use dielectric unions or galvanized steel fittings when connecting to a stainless steel storage tank or boiler. Failure to follow this
instruction can lead to premature failure of the boiler system. Such failures ARE NOT covered by warranty.
