Installing the Water Heater
3.3 Connecting the Gas Supply
WARNING
●
Before connecting the gas supply, determine
the gas type and pressure for the water heater
by referring to the rating plate. Use only
the same gas type indicated on the rating
plate. Using a different gas type will result
in abnormal combustion and malfunction
of the water heater. Gas supplies should be
connected by a licensed professional only.
●
To avoid damaging the connectors on
the water heater, use two wrenches when
tightening pipings to the water heater. Use
one wrench to prevent the connector at the
water heater from turning, and use the other
wrench to tighten the connection. Damaged
connectors may result in system leaks.
●
Properly support the pipings with hangers.
Do not allow the pipings to be supported by
the water heater or its accessories.
●
Ensure that the gas piping is protected
from physical damage and freezing, where
required. Failure to follow these instructions
could result in gas leakage, and result in fire,
explosion, property damage, severe personal
injury, or death.
●
The appliance and its gas connection must
be leak tested before placing the appliance
in operation.
●
To avoid danger of explosion and fire, do not
use flame to check for a gas leak. Perform a
bubble test on the joints to check for gas
leaks. If a leak exists, bubbles will form at
the leaking joint. A gas leak could result
in substantial property damage, severe
personal injury, or death.
●
This water heater cannot be converted from
natural gas to propane or vice versa without
a Navien gas conversion kit. Do not attempt a
field conversion of this water heater without
a Navien gas conversion kit installed by a
qualified service agency.
To mount the water heater to the wall:
1. Ensure that the strength of the wall is sufficient
to support the weight of the water heater.
2. Securely attach the water heater to the wall by
affixing the brackets at the top and bottom of
the water heater.
3. Ensure that the water heater is level using a
leveling tool.
4. The top and bottom mounting brackets are
adjustable to provide flexibility in aligning the
vent with the vent collar on the water heater.
