3. Prior to lifting the boiler onto the wall, use the enclosed template to level and locate the 2 primary (#12 x 3" [3/16" x 3"]) round head

tapping screws, leaving about 1/4" between the screw head and the wall surface to allow for access to the keyway slot located in the

back of the boiler panel. It is extremely important that the line on the template is level when locating the first 2 screws. Failure to do so

will result in an uneven or out of level installation.

4. Remove the boiler cover. Locate the 2 keyway slots over the screws. Then lower the boiler onto the smallest part of the keyway slot.

5. Once the boiler is mounted on the first 2 screws, finish tightening the screws to the back panel. Then install the 6 additional screws of

the same size to the back panel holes. This will provide additional strength and support to the boiler.

PART 5 – BOILER PIPING

Failure to follow the instructions in this section WILL VOID the warranty and may result in property damage, serious 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 a storage tank to supply domestic hot water. HTP offers 60/80/119/175 gallon size storage tanks in either

stainless steel or glass-lined construction. These storage tanks can be directly connected to the boiler supply and return connection.

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 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.

1. The water supply should be shut off while connecting the boiler. A manual control valve must be placed on the inlet connection to the

boiler. Unions can be used on both the hot and cold water lines for future servicing and disconnection of the unit.

2. Purge the water line to remove all debris and air. Debris will damage the water boiler.

3. If the boiler is to be used as a potable water source, it must not be connected to a system that was previously used for non-potable

purposes.

4. Ensure that the water filter on the boiler is clean and installed.

5. New plumbing typically has contamination in the lines. Please flush the system before connection.

The boiler control module uses temperature sensors to provide both high limit protection and modulating temperature control. The

control module also provides low water protection by sensing the water pressure. Some codes/jurisdictions may require additional

external controls.

Never use dielectric unions or galvanized steel fittings when connecting to a stainless steel storage tank or boiler. Use only copper or

brass fittings. Teflon thread sealant must be used on all connections. All piping and components connected to the boiler must be

approved for potable water systems.

The National Standard Plumbing Code, the National Plumbing Code of Canada, and the Uniform Plumbing Code limit the pressure of

the heat transfer fluid to less than the minimum working pressure of the potable water system up to 30 psi maximum. The heat transfer

fluid must be water or other non-toxic fluid having a toxicity of Class 1, as listed in Clinical Toxicology of Commercial Products, 5

Edition.
