Installation continued-
WARNING
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING:
•Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in detection of the gas.
•Most people recognize this odor as a “sulfur” or “rotten egg” smell.
•Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or “fade”, and not be as readily detectable.
•If you have a diminished sense of smell, or are in any way unsure of the presence of gas, immediately contact your gas supplier from a neighbor’s telephone.
•Gas detectors are available. Contact your gas supplier or plumbing professional for more information.
This water heater must be located in an area where leakage of the tank, water line connections, or the combination temperature and pressure relief valve will not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such locations cannot be avoided, suitable drain pan, adequately drained, must be installed under the water heater. The drain pan must have a minimum length and width of at least 4 in. (10.2 cm) greater than the diameter of the water heater and must not restrict proper combustion air flow to the water heater. The drain pan, as described above, can be purchased from your plumbing professional. The drain pan must be piped to an adequate drain. The piping must be at least 3/4 inch (1.9 cm) in diameter and pitched for proper drainage.
It is recommended that a minimum clearance of 4 inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the combination temperature and pressure relief valve.

WARNING
Liquefied petroleum gases/propane gases 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.
IF YOU SMELL GAS:
•Do not try to light any appliance.
•Do not touch any electric 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.

Combustion Air Supply continued-
All combustion air must be supplied from outdoors by one of the following installation methods and as illustrated in Figure 2. 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.
A minimum 34 in2 (86.4cm2) opening area is required to supply fresh air to the water heater for combustion. Cut a 4” x 8 1/2” (10.2cm x 21.6cm) rectangular opening in the outside access door panel with the bottom side of the opening being 6” (15.3cm) from the bottom access door panel. A protective cover for this fresh air opening is suggested to resist the entrance of rodents.
WARNING
Be sure protective cover still allows adequate fresh air opening area.
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 2).
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 is identified on the side of the water heater and HOT water outlet is 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 sw eat fittings are to be use, DO NOT apply heat to the nipples on the w ater heater. Sw eat the tubing to the adapter before fitting the adapter to the w ater connections. It is imperative that heat is not applied to the nipples containing a plastic liner.
