NOTICE
The instructions for the installation of the venting system shall specify that
the horizontal portions of the venting system shall be supported to prevent
sagging; the methods of and intervals for support shall be specified. These
instructions shall also specify that the venting system:
Category IV water heaters must be installed so that horizontal sections have a
slope of at least ¼ inch per foot (21mm/m) to the appliance to prevent
accumulation of condensate; and For Category IV water heaters, where
necessary, have means provided for drainage of condensate.
CAUTION
The GR Series comes from the factory set to use either Natural gas or Liquid
Propane. Confirm the installation gas type matches the gas type on the rating
plate.
Adequate drainage · The appliance should be installed not to damage
the adjacent area. If such locations cannot be avoided, it is recommended that
a suitable drain pan, adequately drained, be installed under the appliance.
The pan must not block combustion air flow.
Connecting the Water Supply · To conserve water and energy, insulate all water
piping–especially the hot and recirculation water lines. Never cover the drain
or pressure relief valve. Having a backflow preventer in the cold water supply
line means that it prevent from thermal expansion backflow. Contact the water
supplier or local plumbing inspector for information about how to control this
situation. If overheating occurs or the gas supply fails to shut off, turn off
the manual gas valve and check the installation.
This installation must conform with below section · “Air for Combustion and

4.4 Venting (Exhaust
The flue temperature of the water heater changes dramatically with changes in
operating water temperature. If the water heater is installed in an
application where the set point is greater than 140°F(60°C, ambient
temperature is elevated, and/or installed in a closet/alcove, CPVC,
polypropylene, or stainless steel material is required. If the system
temperatures are unknown at the time of installation, stainless, polypropylene
or CPVC material is recommended.
The GR Series is a Category IV appliance and may be installed with PVC, CPVC
or polypropylene that complies with ULC-S636, ANSI/ASTM D1785 F441 (see Table
3) or a PVC or stainless steel venting system that complies with UL 1738.
INSTALLATIONS IN CANADA require the use of venting material certified to
ULCS636. All Gas vents connected to the water heater, plastic, stainless steel
or otherwise must be certified to this ULC standard. Appropriate selection of
vent material is very important for proper performance and safe operation of
the water heater.
The flue temperature of the water heater changes dramatically with changes in
operating water temperature. Therefore, it is necessary to assess the
application of the water heater to determine the required certified vent
class. If the water heater is installed in an application where the
Page 16
Bradford White Corporation
outlet water temperature exceeds 145°F, and/ or installed in a closet, class
IIB or higher vent material is required. If the system temperatures are
unknown at the time of installation, class IIB or higher venting material is
recommended.
IN CANADA all venting used must meet the following requirements:
1. ULC-S636 certified and marked
2. The first 3 feet of venting must be accessible for visual inspection.
3. All components used in the vent system must be from a certified
manufacturer.
4 . Vent system components must not be mixed with alternate manufacturers
certified components and/or unlisted components.
5 . The venting must be installed according to the vent manufacturers
installation instructions.
The unit’s vent can terminate through the roof, or through an outside wall.
Vent pipe must pitch upward, toward the vent terminal, not less than 1/4″ per
foot, so that condensate will run back to the water heater to drain. Route
vent pipe to the heater as directly as possible. Seal all joints and provide
adequate hangers as required in the venting system manufacturer’s Installation
Instructions. Horizontal portions of the venting system must be supported to
prevent sagging and may not have any low sections that could trap condensate.
The unit must not support the weight of the vent pipe.
NOTE: For Cascading Installations, please refer to the cascading kit
instructions, available online.
WARNING Use of cellular core PVC (ASTM F891), cellular core CPVC, or Radel®

4.5 General Location Guideline
1. Vent system installation must be in accordance with Local codes or, in the
absence of local codes, the National Fuel Gas Code, ANSI Z224.1 /NFPA 54
and/or CSA B149.1, Natural Gas and Propane Installation Code.
2. The Water Heater is designed to be installed as a Direct Vent (sealed
combustion) type. Be careful to avoid entering foreign substances into the
combustion air. Also, the flue gases must be vented directly to the outdoors
(through wall or roof).
3. Do not install venting system components on the exterior of building
except as specifically required by these instructions
– Vent terminals must be at least 1 foot from any door, window, or gravity
inlet into the building.
– Maintain the correct clearance and orientation between the vent and air
intake terminals. If the vent and air intake terminals must be at the same
height, their center lines must be spaced apart 12 minimum.
– The bottom of the vent and air intake terminal must be at least 12 above the
normal snow line. In no case should they be less than 12 above grade level.
– Do not install the vent terminal directly over windows or doors.
– Air intake terminal must not terminate in areas that might contain
combustion air contaminates, such as near swimming pools.
– For sidewall venting, the minimum horizontal distance between any adjacent
individual Module (Water Heater) vent terminations is twelve (12) inches. It
is better to be far more than 12 inches for avoiding frost damage to building
surfaces where vent terminations are placed.
– The minimum horizontal distance between any adjacent individual module
(water heater) roof vent end piece is one (1) foot.

4.9 Gas Supply and Piping
Gas piping should be supported by suitable hangers or floor stands, not the
appliance.
Review the following instructions before proceeding with the installation.
1. Verify that the appliance is fitted for the proper type of gas by checking
the rating plate. GR Series water heaters will function properly at elevations
up to 10,000 feet (3050 m). Refer to Section 4.12 for High Altitude Settings.
2. Refer to Table 7, Table 8, and Table 9 for sizing piping.
WARNING: Open flame can cause gas to ignite and result in property damage,
severe injury, or loss of life.
NOTE: The GR Series appliance and all other gas appliances sharing the gas
supply line must be firing at maximum capacity to properly measure the inlet
supply pressure. The pressure can be measured at the supply pressure port on
the gas valve. Low gas pressure could be an indication of an undersized gas
meter, undersized gas supply lines and/or an obstructed gas supply line.
3. For minimum and maximum gas supply pressures, see Table 10.
4. Run gas supply line in accordance with all applicable codes.
5. Locate and install manual shutoff valves in accordance with state and
local requirements.
6. A sediment trap must be provided upstream of the gas controls.
7. All threaded joints should be coated with piping compound resistant to
action of liquefied petroleum gas.
8. The appliance and its individual shutoff valve must be disconnected from
the gas supply piping during any pressure testing of that system at test
pressures in excess of 1/2 PSIG (3.45kPa).
9. The unit must be isolated from the gas supply system by closing its
individual manual shutoff valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than 1/2 PSIG (3.45kPa).
10. The appliance and its gas connection must be leak tested before placing
it in operation.
11. Purge all air from gas lines.

4.9 Gas Supply and Piping (continued)
The gas connection fitting on the unit is 3/4 male NPT.
The supply line must be sized for the maximum output of the water heater model
being installed. If there are additional gas appliances from the main supply
line, you must measure sizes of the supply line according to the COMBINED
total maximum BTU/hr draw for the appliances as if they were all operating at
the same time.
Measure the length of the gas supply line from the gas meter to the Water
Heater. Use the tables in this manual or refer to the gas line manufacturers
sizing information to determine the correct supply pipe size.
The gas shut-off valve in the gas supply line should be installed close to the
unit.
To facilitate any future maintenance, it is also recommended that an approved gas union fitting be installed in the supply line between the shut-off valve and the 3/4 male NPT connection on the Water Heater.
- Install an approved gas line pipe to gas line connection under the Water Heater. Include manual shut off valve and gas union connection, as shown.
- Test gas pressure to make sure it meets the minimum standards and does not exceed the maximum standards for the water heater.
- Leak test the gas line pipe before placing the unit in operation. Use
approved leak detector liquid solutions only to check for leaks.
Do not operate the water heater until all connections have been completed and the heat exchanger is filled with water.
Water Heater MUST be installed downstream of the gas meter for adequate gas supply.

4.16 Disposal of Condensate
High efficiency gas condensing Water Heaters create condensation when
operating. Condensation has acidic (pH) of approximately 4-5.
Condensate must be drained in accordance with all local regulations. Follow
your local code with regards to the disposal of condensation. One of 3
disposal methods must be followed 1. to floor drain 2. to neutralizer drain
(optional kit * ) 3. to condensate pump (field supplied)
If a neutralizer is installed, periodic replacement of the lime stone (or
neutralizing agent) will be required. The rate of depletion of the lime stone
varies upon usage of the Water Heater. During the first year of operation,
please check the neutralizer every few months for depletion.
Apply only corrosion-resistant materials for the condensate drain lines such
as 1/2 PVC, CPVC, Polypropylene pipe.
NOTICE
Category IV water heaters must be installed with a means provided for the
drainage of condensate.
AVIS
Catégorie IV chauffe-eau doit être installé avec une moyens prévus pour
l’évacuation des condensats.
CAUTION Condensate is mildly acidic (pH=5), and may harm some floor drains
and/or pipes, particularly those that are metal. Ensure that the drain,
drainpipe, and anything that will come in contact with the condensate can
withstand the acidity, or neutralize the condensate before disposal. Damage
caused by failure to install a neutralizer kit or to adequately treat
condensate will not be the manufacturer’s responsibility.

5.5 DHW Set Point Change Mode
The GR Series has a built in water flow limiter and will automatically adjust
the flow rate up or down based on outlet temperature at the inlet side of the
water heater. If the temperature drops below the set point, and the water
heater is at full fire, the inlet flow to the heat exchanger will be reduced.
Therefore, the outlet temperature will begin to rise to the desired set point.
If the temperature begins to rise above the set point the flow will increase
until full flow is reached. This feature ensures that the outlet water is
always the ideal temperature for the user.
If this feature is not desired, then the `over-ride’ to this feature must be
turned OFF.
1. Turn off the power to the Control Display. 2. Move DIP switch 4 to the OFF
Position.
Set Point Change Modes The display shows the following information when changing water heating temperature set points.

Troubleshooting
7.1 Diagnostics Before calling for service, review the following diagnostic
steps first for saving time and money.
Question & Answer
Indicate Burner does not ignite even if hot water is opened.
Outlet water is not hot enough.
Outlet water is too hot.
Indicator Make sure that the ON/OFF button on the Control Panel has been
turned ON. If the monitor on the Control Panel is blank, make sure the power
cord is plugged and fuses on the main controller in the units are good. Make
sure that there is water supplied to the unit. The heater will be running when
the inlet water flow sensor detects the flow over 0.5gpm. Make sure the cold
and hot water valve are not plumbed in reverse.
Make sure that cold water and gas supply lines are opened.
Make sure that water lines are not frozen.
Make sure that the set point temperature on the unit is not too low.
Make sure that the filter in the cold water inlet line is not clogged with
debris.
Make sure that the gas supply type is correct.
Check if the supply and manifold gas pressures are in accordance with
specifications. Make sure that the water flow sensor with three wires has been
properly connected on the main water valve. Make sure that the set point
temperature on the unit is not too hot.
Make sure that the filter in the cold water inlet line is not clogged with
debris.
Make sure that the gas supply type is correct.(Check the provided gas with the
water heater model)
Hot water temperature
Make sure that the filter in the cold water inlet line is clean. Check if the supply gas pressure is sufficient.
