Selecting an Installation Site
1. Select an interior location for the installation. Each
installation is unique; therefore, take the time to fi nd the
best location for the water heater.
a. Install the water heater near locations that use hot
water, such as bathroom, kitchen, or laundry room
faucets.
b. Select a location that minimizes the length of the
water pipe.
c. If the distances are long or if the faucet or appliance
requires “instant” hot water, we recommend running
a recirculation line back to the water heater from the
furthest fi xture. Insulate the hot water supply and
recirculation lines.
IMPORTANT
When installing this water heater, follow all local
building codes and the current edition of the National
Fuel Gas Code (ANSI Z223.1/NFPA 54) in the USA or
National Gas and Propane Installation Code (CAN/CGA
B149.1) in Canada, when installing this product.
d. Select a location away from foot traffi c and away
from areas where dust, debris, chemical agents, or
other combustible materials could accumulate.
e. Allow suffi cient space for service and maintenance
access to all gas, water, and drain connections.
f. Make sure the location meets all building code
requirements.
g. Make sure the wall surface the water heater is
mounted onto will support the weight of the unit.
SAFETY
INSTRUCTIONS
The Hubbell .. 200 and GX 250 water heaters weigh 90 lbs. The
GX 200P and GX 250P weigh 98 lbs.
2. Minimize the distance that the exhaust gas vent and
fresh air intake must travel to an exterior wall.
a. The exhaust vent outlet must not be located next to
a walkway, near soffi t vents, crawl space vents, or
other areas where condensate (water vapor) could
cause damage or create a hazard.
b. The fresh air inlet vent must be located at least 12”
from the exhaust vent.
c. Contaminated or dirty air drawn into the intake
pipe can damage the water heater. The
Hubbell
warranty does not cover damage caused by
airborne contaminants.
IMPORTANT
Reduce the maximum equivalent length by 5 feet
per 90° elbow and by 2 feet per 45° elbow. Intake
and exhaust venting pipes have the same allowable
lengths. Do not exceed these set limits.
EXAMPLE
: A 3” vent line or fresh air intake line
(Model
GX200
) with the six 90 degree elbows
would
be limited to a length of 70 feet in a twin
pipe configuration
3. Locate the unit close to a drain and near gas and water
connections.
The water heater produces a signifi cant amount of
condensate during normal operation and should be
located near a suitable drain where damage from
a possible leak will be minimal. Installing the water
heater in a location without a drain will void the
warranty and
Hubbell
will not be responsible for
any resulting water damages that may occur as a
result. For additional information, refer to the Install
Condensate Drain section.
The water heater should be located in an area where
leakage from the unit or water pipes will not result in
damage to the area around the appliance or to lower
fl oors of the structure. When such locations cannot
be avoided, it is recommended that a suitable drain
pan, adequately drained, be installed under the water
heater. The pan must not restrict combustion air fl ow.
