WHEN YOU RECEIVE YOUR NEW WATER HEATER
Check the new equipment to see if all components are in good condition. If damage is observed
or parts appear to be missing, contact your wholesaler.
WATER HEATER PLACEMENT
This water heater must be located in an area where leakage of the tank, water line
connections, or the 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 lo-
cation cannot be avoided, a suitable drain pan must be installed under the water
heater. The drain pan depth must be suitable for draining and collecting water. The
drain pan can be purchased from your plumbing professional. The drain pan must be
piped to an adequate drain and all drain piping must be at least 0.75" in diameter
and pitched for proper drainage. The pan must not restrict combustion air flow.

holes are aligned as shown in Figure 2. Consult with local code officials before using this
method. Please consult local codes, NFPA 54 and/or contact Bock Water Heaters with questions
concerning proper flooring materials. Leave adequate room for periodic maintenance of heater
and burner. The water heater should be placed as near to the chimney as practical in order to
keep vent connector length to a minimum. Consult National Fuel Gas Code for proper vent con-
figuration.
Minimum clearance to combustible construction is: SIDES 6"; BACK 6"; FRONT 24";
DRAFT HOOD; 18". The installation of this water heater must conform with local
codes and ordinances. In the absence of local codes, the installation must comply
with the National Fire Protection Association (NFPA 54) Code.
HIGH ALTITUDE
The water heaters covered in this manual are approved for installation at "low" altitudes (0 -
2,000 ft.) and "high" altitudes (2,000 - 7,700 ft.) with natural gas. For LP gas installations at
high altitude, contact Bock Water Heaters.
For natural gas installations at high altitude, the standard (low altitude) orifice can be used at
the preset gas valve manifold pressure (3.5" W.C.). Due to a reduced gas energy content (heat-
ing value) and/or a lower atmospheric pressure at high altitude, there will be a reduction in
input rate at the burner with the standard orifice. For these water heaters, this input rate re-
duction is enough to offset the effects of lower oxygen content in the air at high altitudes up
to 7,700 feet. Refer to the rating plate on the water heater for maximum input ratings at low
altitude (also see Table 1) and high altitudes (given at 5,400 feet and 7,700 feet).
For natural gas installations at altitudes above 7,700 feet, contact Bock Water Heaters.
Atmospheric Gas
CAUTION
Locate the heater so it is not subject to physical damage from
moving vehicles or flooding. Do not locate the water heater in a
room where swimming pool chemicals or large quantities of water
softener salt are kept. Installing a water heater in this environ-
ment will result in premature failure of tank and burner compo-
nents due to corrosion caused by these elements
diffusing into the air.
DO NOT INSTALL THE WATER HEATER ON COMBUSTIBLE
FLOORING. Place on noncombustible flooring and maintain clear-
ances prescribed by this manufacturer and per code NFPA 54. If the
water heater must be located on combustible flooring it must be
raised off the floor with a layer of 4'' concrete block laid so the air
