Water Piping - onsen ON-I14L-LP Manuel D'installation Et D'utilisation

5
Use only approved materials to connect the unit to the gas line.
6
Install a manual gas valve in the gas supply line to the water heater. For best performance, the water heater
should be the first user downstream from the gas supply meter.
7
Purge the gas line of any debris before connection to the water heater.
8
Connect to the water heater.
Leak check all joints including the heater for gas tightness. Use a leak detection solution, soap and water, or
9
an equivalent nonflammable solution, as applicable.
WARNING

WATER PIPING

1
All piping, including soldering material, and components connected to this heater shall be approved for use
in potable water systems.
2
If the heater was previously used for heating non-potable water, do not install the heater into a potable
water system.
3
The installation of manual shutoff valves, drain valves and unions is recommended. A professional should
review each installation and ensure adequate ability to isolate, drain, and disconnect heater for service
needs.
4
Connect suitable piping from water supply to the water heater. Note the water heater connections are ½"
NPT.
5
This unit requires a pressure relief valve. The relief valve must be installed near the hot water outlet.
6
Purge the water line to remove debris and air. Debris can plug and damage the heater.
7
Install the inlet water filter at the cold water inlet. Ensure the filter is easily removable for inspection and
cleaning.
8
Test water connections for leaks. Turn on water and purge water through the water heater and system.
Flow for 1-2 minutes. Ensure all air is eliminated.
9
After filling and flushing the system, check the inlet water filter for debris and clean as required.
10
Consider insulation on hot water piping for energy conservation and personal protection. Do not insulate
the pressure relief valve!

Ensure any leak check solution is non-corrosive and is completely rinsed from the
piping after leak check is complete. Corrosion of the gas piping and subsequent leaks
could occur. Never use flammable solutions or an open flame to test for gas leaks!
