QUICK REFERENCE INSTALLATION GUIDE

The quick reference illustrations show the installation of two GX200P water heaters connected together

with a storage tank. Installation of a single unit or up to five units is basically the same. When installing multiple units, refer to the Multiple Units section for additional information.

1. Select a location. Note that the piping can be conﬁ gured to enter or exit the unit from either the left or right side, as viewed from the front.

2. Mount the water heater(s) to the wall.

Attach two 2x4 mounting blocks (at least 23” for a single unit or 46” long for two units) to the wall. The uppermost mounting boards should be at the desired height for the top of the unit.

IH-80

e. Hang the unit on the mounting bracket. If multiple

units are installed, the spacing between the units should be approximately 6”.

IH-81

3. Install the gas lines, as shown in the illustration.

Attach a second mounting block 14” (center to center) below the upper mounting block.

c. Attach metal mounting bracket(s) to the upper

mounting block approximately 3” on either side of the center and 1/2” down from the top of the mounting block.

Adjust and tigthen the bottom bracket to the units so that the unit to hangs vertically on the wall.

IH-82

a. Temporarily place a short section of 3” schedule

40 PVC pipe on one of the air inlets in order to judge clearance allowances as the gas piping is assembled.

b. Due to limited wall clearance, connect the union as

your ﬁ nal step of gas piping.

c. Check for gas leaks at this point in the assembly

process.

QUICK REFERENCE INSTALLATION GUIDE

Water Connections

4. Install the combustion air inlet and ﬂ ue gas outlet PVC piping.

Note: The inlet and outlet pipes from the unit are 3” diameter while the header piping is 4” diameter, as shown in the illustration. The larger header piping is required whenever multiple units are installed.

6. Install and connect the cold water lines.

IH-85

7. Connect and route the condensate trap and drain line to an appropriate discharge site or drain.

IH-83

5. Install and connect the hot water lines. If an optional hot water storage tank is required, connect the hot water lines to this tank. If required, install a pressure relief valve or a temperature and pressure relief valve.

PREPARATION BEFORE INSTALLATION

Selecting an Installation Site

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.

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.

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.

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.

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 GX250 water heaters weigh 90 lbs. The GX200P and GX250P 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.

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.

PREPARATION BEFORE INSTALLATION

4. Locate the water heater and all water pipes in an area where the ambient temperature always remains above freezing.

NOTICE

In cold climates, if there is a power failure, the unit’s freeze protection system will not operate, and can result in water freezing inside the heat exchanger.

To prevent damage to the water heater, turn OFF the gas supply and inlet completely drain the unit.

Damage caused by freezing water is not covered by the Hubbell warranty.

a. When the water heater is connected to an electrical

power supply, it will automatically prevent the water inside the unit from freezing.

b. The unit’s freeze protection system will not prevent

the water in surrounding pipes from freezing.

water valve. Open the drain valve and

5. Select an appropriate location for the combustion air and exhaust pipes to exit the house. Use the diagram and chart on the next page to make this determination.

High Elevation Installations

For operation at elevations above 2,000 feet, Hubbell model ratings should be reduced by 4% for each 1,000 feet above sea level.

Water Quality

Potable water is defined as drinkable water supplied from utility or well water in compliance with EPA secondary maximum contaminant levels (40 CFR part 143.3) as shown in the table below. If your water contains contaminants higher than outlined by EPA, then water treatment is recommended and additional maintainence may be required. If you suspect that your water is

contaminated in any way or water heater errors occur, discontinue use of the water heater and contact an authorized technician or licensed professional.

GAS CONNECTION

WARNING

FIRE AND/OR EXPLOSION HAZARD To avoid serious injury or even death, the gas line installation and the gas line inlet pressure test must be done by a licensed professional.

Always match the water heater with the type of gas supplied to the unit (natural gas or LP gas). The water heater is factory preset for natural gas.

Make sure the gas line pressures are within normal limits. Pressures outside normal limits can result in poor performance and hazardous operating conditions.

Determine if the Hubbell water heater will use natural gas (factory preset) or LP (propane) gas.

a. To convert the unit to propane, refer to the Propane

(LPG) Conversion section in this manual.

b. Make sure your gas supply matches the rating decal

located on the side of the water heater.

2. Make sure the gas pressure meets the requirements for the unit, as shown in the tables.

b. Measure the length of the gas supply line from the

gas meter to the water heater or other appliances requiring gas.

c. Use the Gas Pipe Sizing tables in this manual or

refer to the gas line manufacturers sizing information to determine the correct diameter for the supply pipe.

d. The diameter of the gas lines, shown in the

illustration, will vary according to the speciﬁ c installation requirements.

NOTE: Always clean the inside of the gas line of any dirt or debris before connecting the piping to the unit.

4. Install a gas union connection with a short piece of 3/4” NPT pipe.
