Carbon monoxide
The installation of carbon monoxide detectors is highly
recommended by the U.S. Consumer Product Safety
Commission for buildings with gas burning equipment.
Sources of carbon monoxide include exhaust vents for
gas appliances or wood burning replaces that are not
properly vented, malfunctioning furnaces and exhaust
fumes from idling cars.
Carbon monoxide is a colourless and odourless gas
that is highly toxic. It can interfere with the delivery
of oxygen by the blood to the body. Exposure to low
levels of CO can cause headaches, confusion, nausea,
dizziness, fatigue, and shortness of breath. High level
exposure of CO can cause impaired vision, convulsions,
coma and possibly death.
Have a qualied service technician inspect the heating
equipment exhaust vent pipes and chimney ues on a
yearly basis.
In winter, inspect the exhaust vents for the dryer,
furnace, wood burning or gas stove, replace and heat
recovery ventilator to ensure they are not obstructed
by snow build-up.
Carbon monoxide detectors should be installed and
maintained in buildings that house gas burning
equipment. It is recommended to use a carbon
monoxide detector that is in compliance with a
nationally recognized standard such as ANSI/UL 2034-
2002 or CSA 6.19-01.

Safety Information and Codes
Water pipe freezing hazard
WARNING
Serious property damage and/or personal injury can
occur if the pipes are not protected from
freezing resulting in the pipes bursting. The boiler
may also shut down. Turn off the water supply and
drain the water pipes or protect them from freezing
when leaving the home unattended for long periods
of time during very cold weather conditions.
The boiler is designed to provide a comfortable
and warm environment and is not designed for the
prevention of frozen water pipes. In case an unsafe
condition occurs, the boiler has been designed and
equipped with several safety devices that will shut
down the boiler and stop it from restarting.
If the boiler is dormant for an extended period of time
during cold winter weather, the water pipes may freeze
and burst which can result in extensive water damage
and lead to mold growth. A variety of molds can cause
serious health and respiratory problems. If water
damage should occur, immediately dry the affected
areas to avoid the possibility of mold growth.
If the building will be empty for an extended period of
time in old winter conditions, then the following steps
should be taken:
• Turn off the building’s water supply, drain the pipes
and add some antifreeze for potable water for the
toilet tanks and drain traps.
• Have the building monitored and checked during
cold winter weather and call a qualied service
technician if necessary.
• Remote temperature sensors are available which
will alert someone if freezing conditions occur in the
building.

Clearances
The GT 530A/AE boiler has a sturdy underframe,
it does not need any special base although a house
keeping pad is recommended to keep steel parts out
of casual water. Its combustion chamber is closed, so
it is not necessary to place it on a reproof oor, but
the oor must be able to bear the weight of the boiler
subject to state and local code NFPA 31 and state Fire
Marshall.
The minimum dimensions shown on the following
drawing are provided as recommendations and
guidelines for service access.
If A= 471/4” (side burner side door open),
A’=471/4” (side burner door open): dimensions to be
adopted according to the space required for the burner
when the door is open.
Dimensions “X” = burner length plus 24 inches for
service

ments.
Replacement procedures
________________________________________________________________________________________________________________________________________________________
• When an existing boiler is removed from a common
venting system, the common venting system is
likely to be too large for proper venting of the
appliances remaining connected to it.
• At the time of removal of the existing boiler,
the following steps shall be followed with each
appliance remaining connected to the common
venting system placed in operation, while the other
appliances remaining connected to the common
venting system are not in operation.
(a) Seal any unused openings in the common venting
system,
(b) Visually inspect the venting system for proper
size and horizontal pitch and determine there is
no blockage or restriction, leakage, corrosion and
other deciencies which could cause an unsafe
condition,
(c) Insofar as is practical, close all building doors and
windows and all doors between the space in which
the appliances remaining connected to the common
venting system are located and the other spaces
of the building. Turn on clothes dryers and any
appliance not connected to the common venting
system.
Turn on any exhaust fans such as range hoods
