State Industries ULTRA FORCE 101 - Manual (Page 13)

There is a risk in using fuel burning appliances such as gas water
heaters in rooms, garages or other areas where gasoline, other
flammable liquids or engine driven equipment or vehicles are
stored, operated or repaired. Flammable vapors are heavy and
travel along the floor and may be ignited by the water heater’s
igniter or main burner flames causing fire or explosion.
Flammable items, pressurized containers or any other potential
fire hazardous articles must never be placed on or adjacent to
the water heater.
clearance to combustible materials
The water heaters covered in this manual are approved for
installation on combustible flooring. The clearance to combustible
and non combustible construction materials is 0 inches on the
back and sides of the water heater. These water heaters are also
approved for installation in an alcove.
note: Adequate clearance for servicing should be maintained
on all installations. See Service Clearance below.

serVice clearance
A service clearance of 24 inches (61 cm) should be maintained
from serviceable parts such as the T&P valve, control system
components, gas valve, clean out opening, drain valve, the vent
connection (exhaust elbow) and the condensate drain. Leave as
much room as possible above the water heater and near the
exhaust elbow for this reason. See Figure 9 on page 17.
intake air and Vent pipe clearances
The minimum clearance from combustible materials for the vent
(exhaust) and intake air piping shall be 0 inches. Vent or intake
air piping passing through a combustible wall or ceiling must be
a continuous run (no joints).
extended Vent terminations
The water heaters covered by this manual can be installed using
3 inch pipe for the intake air and/or vent piping up to a maximum
of 50 equivalent feet (15.2 m). The intake air and/or vent piping
can be extended up to 120 equivalent feet (36.5 m) by installing
4 inch pipe. See the Venting requirements on page 24.
The water heater ships from the factory with two (2) 3 inch
terminations that are 45° PVC elbows with a debris screen
installed. When 4 inch intake air or vent pipe is installed, factory
supplied 4 inch terminations must be used.
Contact your local distributor or call the parts department phone
number listed on the back cover of this manual to order 4 inch
termination(s).
optional concentric terminations
The water heaters covered in this manual can be installed in a
Direct Vent configuration using an optional concentric termination.
See Concentric Termination installation on page 30.
hard water
Where hard water conditions exist, water softening or the
threshold type of water treatment is recommended. This will
protect the dishwashers, coffee urns, water heaters, water
piping and other equipment. See maintenance on page 64 for
sediment and lime scale removal procedures.
circulation pumps
A circulating pump is used when a system requires a circulating
loop or there is a storage tank used in conjunction with the water
heater. See the Water Piping Diagrams beginning on page 71
for installation location of circulating pumps.
See Circulation Pump Wiring Diagrams on page 70 for
electrical hookup information. install in accordance with the
current edition of the National Electrical Code, NFPA 70 or the
Canadian Electrical Code, CSA C22.1.
All-bronze circulating pumps are recommended for used with
commercial water heaters.
Some circulating pumps are manufactured with sealed bearings
and do not require further lubrication. Some circulating pumps
must be periodically oiled. refer to the pump manufacturer’s
instructions for lubrication requirements.
insulation blankets
Do not obstruct water heater air intake
with insulating blanket.
Gas and carbon monoxide detectors
are available.
Install water heater in accordance with
the instruction manual.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Breathing Hazard - Carbon Monoxide Gas
insulation blankets are available to the general public for external
use on gas water heaters but are not necessary with these
products. The purpose of an insulation blanket is to reduce the
standby heat loss encountered with storage tank heaters. The
water heaters covered by this manual meet or exceed the Energy
Policy Act standards with respect to insulation and standby heat
loss requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this
heater, you should follow these instructions. See the Features
and Components section of this manual for identification of
components mentioned below. Failure to follow these instructions
can restrict the air flow required for proper combustion, potentially
resulting in fire, asphyxiation, serious personal injury or death.
•
do not apply insulation to the top of the water heater, as this
will interfere with safe operation of the blower assembly.
• do not cover the control system LCD on top of the water heater.
• do not cover the Temperature-Pressure relief Valve.
• do not cover the instruction manual. keep it on the side of the
water heater or nearby for future reference.
• do obtain new warning and instruction labels from the
manufacturer for placement on the blanket directly over the
existing labels.
• do inspect the insulation blanket frequently to make certain it
does not sag, thereby obstructing combustion air flow.
