Navien Gas Water Heater Installation

Locating the Water Heater:
Location selection may not necessarily affect the operation of the
Navien water heater but it will affect the customer’s experience and level
of satisfaction with the product. Understanding that each building is
different, the contractor will have to select the best location based on a
combination of the following factors:
1. Locate Navien Water Heater close to a drain where condensed water and possible
water leakage will not damage to surrounding areas. A significant amount of
condensed water will be produced each time the water heater is used. In addition,
as with any water heating appliance, the potential for leakage at some time in the
life of the product does exist. If there is no drain, Navien will not be responsible for
any water damage that may occur.
2. Locate where the domestic water supply comes into the building.
3. Locate where the gas supply comes into the building.
4. Locate the unit close to the main fixtures in the home (bathrooms, kitchen, laundry,
etc.). Select a location that minimizes the water piping distance between the major
fixtures.
If the distances are long or an appliance needs “instant” hot water, Navien
recommends using its
“A” models and running a recirculation line back from the
furthest fixture. Insulate as much of the hot water supply line and recirculation line
as possible.
5. Consider Venting Options: Select a location that minimizes the amount of venting
required. Consider venting restrictions from windows, doors, air intakes, gas meters,
neigh
bor’s houses, etc.
Maintain proper clearances from any openings in the building (see chart in
venting section).
Navien Water Heater requires a minimum clearance of 12 inches above the
exterior grade.
Do not install the water heater where moisture from the exhaust may cause
discoloration or damage to walls.
Install the exhaust vent so that there are no obstacles around the termination and
so that exhaust cannot accumulate.
Do not enclose the termination.
Do not install the water heater near vents for heating or cooling. A minimum of 4
feet (1.2m) should be maintained.
6. It is not recommended to install the Water Heater in bathrooms, bedrooms, any
occupied rooms normally kept closed, or in indoor areas without proper venting.
