VENTING
WARNING
The vent system must be installed properly. Failure to properly install the vent system could result in property damage, personal injury, or death.
Make certain the flue baffle is in place and centered in flue tube. Place the draft diverter over the flue opening at the top of the water heater by inserting the tips of the draft diverter legs into the four (4) holes provided in the water heater top. Cut a 7 1/4 inch (18.5cm) diameter hole in the ceiling and roof directly above the flue of the water heater. Center the water heater beneath the 7 1/4 inch (18.5cm) diameter holes in the roof and ceiling for proper alignment of the draft diverter and roof jack vent. Apply non-hardening mastic on the roof, around the previously cut hole, to form a weather seal with the flashing of the gas vent roof jack assembly. Insert gas vent roof jack assembly from above and fasten the flashing to the roof through the pre-punched holes in the flashing. Note: Only the roof jacks listed in Figure 4 can be used on this water heater. Apply additional non-hardening mastic to complete the weather seal. Slip the 3inch (7.62cm) vent connector extension that is shipped telescoped, into the gas vent roof jack assembly down onto the draft diverter that is secured to the top of the water heater and fasten with the two
(2) sheet metal screws provided.
COMBUSTION AIR SUPPLY
WARNING
Liquefied petroleum gases/propane gas are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor.
WHAT TO DO IF YOU SMELL GAS
•Do not try to light any appliance.
•Do not touch any electrical switch; do not use any telephone in your building.
•Immediately call your gas supplier from a neighbor’s telephone. Follow the gas supplier’s instructions.
•If you cannot reach your gas supplier, call the fire
department.
DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!
IMPORTANT
The flow of combustion and ventilating air must not be obstructed.
All combustion air must be supplied from outdoors by one of the following installation methods and as illustrated in (Figure 4). The flow of combustion and ventilating air must not be obstructed. Adequate air must be supplied for combustion and ventilation. An insufficient supply of air will cause recirculation
of combustion products resulting in air contamination that may be hazardous to life. Such a condition often will result in a yellow, luminous burner flame, causing carboning or sooting of the combustion chamber, burners and flue tubes with possible damage to the heater.
Air Intake Installation - An optional 3" (7.6cm) diameter telescoping air intake and leg enclosure are required to supply fresh air to the water heater for combustion for 30 gallon (113.5L) water heaters and for 40 gallon (151.4L) water heaters. Note: When a mobile home is tightly skirted, an air inlet opening in the skirting must be provided. The opening shall have a minimum free area of at least 9 in2 (22.9cm2). If the opening is screened or covered with a louver, the total free area must be at least 9 in2 (22.9cm2). The following steps must be followed for proper installation of these air supply components: (Refer to Figure 4.)
1.After selecting the proper location for the water heater, cut a 4" 10.2cm) diameter hole through the floor and all other layers of flooring and sheathing directly beneath the center of the water heater.
2.Insert the air intake into the 4" (10.2cm) diameter hole and fasten to the floor with the screws provided.
3.Adjust the air intake so the lower tube is extends below the underside sheathing and secure with the screws provided. THE BOTTOM OF THE
AIR INTAKE MUST BE AT LEAST 12" (30.5cm) ABOVE THE GROUND LEVEL.
4.Seal the openings around the air intake and underside sheathing to resist the entrance of rodents.
5.Position the water heater so it is centered above the air intake. (Note:
The water heater should also be centered with the openings in the roof and ceiling to allow for correct assembly of the roof jack to the draft diverter.)
The water heater is to be secured in place using the supplied sheet metal strapping and screws. Fasten the base of the water heater to the floor using the screws provided. The perforated metal strapping must be fastened to the top of the water heater and to the adjacent walls with the screws provided (See Figure 4).
WATER CONNECTIONS
NOTE:
BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE.
After shutting off the main water supply, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the water heater. After the pressure has been relieved, close the faucet. The COLD water inlet and HOT water outlet are identified on the top of the water heater. The fittings at the cold water inlet and hot water outlet are dielectric waterway fittings with 3/4" NPT male thread. Make the proper plumbing connections between the water heater and the plumbing system to the house. Install a shut-off valve in the cold water supply line.
CAUTION
If sweat fittings are to be use, DO NOT apply heat to the nipples on top of the water heater. Sweat the tubing to the adapter before fitting the adapter to the water connections. It is imperative that heat is not applied to the nipples containing a plastic liner.
WARNING
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED ¾” X ¾” TEMPERATUARE AND PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM EXCESSIVE TEMPERATURE AND PRESSURES.
