Venting - Bradford White RG1D Installation & Operation Instructions

Venting

The venting system must be installed properly following all local codes or
in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1-
Latest Edition, or in Canada, The Natural Gas and Propane Installation
Code, B149-Latest Edition. Failure to properly install the venting system
could result in property damage, personal injury, or death.
This water heater has been shipped with a draft hood, also called a draft
diverter, for which it was designed. The water heater must be operated with
this draft hood properly installed on the damper bracket. If ever removed, the
draft hood must be replaced in the same position and properly secured.
Carefully inspect the venting system of a replacement water heater
installation before connecting to the venting system. All joints in the vent
connector must be securely fastened with screws and fit tightly together.
Inspect the venting system for signs of deterioration (rust and perforation)
and replace any sections that are not in good condition.
The chimney must be lined and in good condition. Check to make sure the
venting system is properly sized for the water heater. If the venting system
was previously sized for another gas appliance that has been removed, the
venting system may now be too large. Refer to the National Fuel Gas Code
ANSI Z223.1-Latest Edition, or in Canada, the Natural Gas and Propane
Installation Code, B149-Latest Edition, for the correct sizing of venting
systems and common venting with another gas appliance.
Do not vent this water heater into the venting system of another gas
appliance designed to vent under positive pressure.
The water heater should be installed as close as practical to the venting
system to minimize the vent connector length required. Refer to local codes
for the distance limitations on vent connector lengths.
At the completion of the water heater installation, the burner and venting
system must be checked for proper operation with all other commonly
vented appliances in operation. Check for spillage of flue products around
the outside relief opening of the draft hood after several minutes of
operation. The flame from a match should be drawn into the draft hood. Do
not use the water heater or connected equipment if spillage is detected until
the problem is corrected. Refer to the latest edition of the National Fuel
Gas Code, or in Canada, the Natural Gas and Propane Installation Code for
complete details on the "Procedure to Be Followed to Place Equipment in
Operation."
