ATTACHING THE WATER SUPPLY
1)
The unit is supplied with 3/4” NPT fittings molded into the heating chamber. DO NOT USE PIPE DOPE
OR PVC PRIMER OR GLUE ON THE FITTINGS. DO NOT USE A TORCH ON ANY FITTING CONNECTED TO
THE HEATER. Use only TEFLON TAPE on the threads ensuring that no tape or debris enters the heater.
2)
If an adapter is required to reduce fitting size, use the enclosed adapters with gasket and seal with
Teflon tape. For other adapters, be sure to use 3/4 NPT fittings and seal with TEFLON TAPE ONLY.
Connect plumbing to the adapters with Teflon tape. Do not reduce below ¾ for whole house extender
applications to avoid flow restrictions.
3)
Flex-‐pipe is recommended for ease of installation and service. Where fixed pipe is used, a plumbing
union is recommended for ease of service.
4)
Always use two wrenches to tighten plumbing fittings to the heater to avoid stress to the fittings and
heating chamber.
5)
Install ball valves on the inlet and outlet pipes with a bypass to allow isolation of the heater for service.
Be sure both inlet and outlet valves are open prior to activating the heater.
6)
For installations above the ceiling or attic, a bleed air separator is recommended. Where water
hammer exists, a properly sized arrestor should be installed.
7)
Run water through the unit for a few minutes until all visible air is purged from the lines and unit and
the flow is continuous without spitting air.
