SECTION II –
INSTALLATION
WARNING / CAUTION
For protection against excessive pressures and temperatures, local codes require the installation of a
temperature-and-pressure (T&P) relief valve certified by a nationally recognized laboratory that
maintains periodic inspection of production of listed equipment of materials, as meeting the
requirements for Relief Valves and Automatic Gas Shutoff for Hot Water Supply Systems. ANSI
Z21.22-1971.
The National Fuel Gas Code, (ANSI Z223.1 and Can 1 -Bl 49.1 or Bl 49.2), expressly prohibits the
following:
1. Installation of water heater in a bathroom, bedroom, or any occupied room normally kept
closed.
2. Installation of a water heater in a garage unless the unit is installed so that the burner and
ignition devices are at least eighteen (18) inches above floor level and protected to avoid
damage by a moving vehicle.
If unit is painted or insulated on the job site, care should be taken not to paint or insulate over the
A.S.M.E. nameplate. This plate should be accessible and legible at all times to inspectors, and
information from this plate must be used when ordering parts from the factory.
HANDLING
Some models have been constructed with lifting lugs to permit lifting with a crane. Fork lift
movement (rear access only) is also acceptable.
To lift with a crane, remove flue outlet adapter and connect a lifting cable to the two lifting lugs
attached to the top tubesheet. Be sure lifting cable and crane can support the shipping weight as
shown on Bill of Lading.
The skids are compatible with the forks of most fork lift equipment. When moving a heater into
place, pick water heater up from rear (do not pick up from front or sides) with forks inside the skids.
Picking up heater on outside of skids may allow forks to puncture bottom of combustion chamber.
INSPECTION
Inspect the water heater and burner for possible damage that may have occurred in shipping or during
storage. Check rating plate on the water heater and burner for compliance with specifications. Be
sure the electrical supply, gas and/or oil supply lines are adequate for the installation.
