Re-Starting The Heater After Shut-Down
• Flammable hydrogen gases may
be present.
• Keep all ignition sources away
from faucet when turning on hot
water.
Explosion Hazard
WARNING
Caution: Hydrogen gas can be produced in a hot water
system served by this heater that has not been used for a long
period of time (generally two (2) weeks or more). Hydrogen
gas is extremely flammable and can ignite when exposed
to a spark or flame. To reduce the risk of injury under these
conditions, it is recommended that the hot water faucet be
opened for several minutes at the kitchen sink before using
any electrical appliance connected to the hot water system.
Use caution in opening faucets. If hydrogen is present, there
will probably be an unusual sound such as air escaping
through the pipe as the water begins to flow. There should be
no smoking or open flame near the faucet at the time it is open.
1. Follow instructions for "Filling The Water Heater" and
"Startup" when heater is ready to be put back into service.
2. If the heater does not start, check to see if the relay on
the burner has tripped. Reset if necessary. Check to see
if the thermostat is set at “Normal” or “High”.
3. If the heater does not start:
a. Turn "OFF" the electrical supply to the water heater.
b. Shut off the oil supply at the tank.
c. Call a qualified Oil-Burner Technician.
VI) COMBO HEATING
WARNING
Keep the area around the heater clear and
unobstructed.
This section serves as a guide for the installation and use
of “Combo” heating systems utilizing a domestic water
heater that has been specifically approved for such use. It is
written for those knowledgeable in the required trades and
professionals involved in the design and installation of Combo
Heating Systems.
It is the responsibility of the installer/designer to follow all
applicable codes to ensure the effectiveness and safety of
the installation.
This appliance has been design certified as complying with
American National Standard/CSA Standard for water heaters
and are considered suitable for Water (Potable) Heating and
Space Heating. Note: This water heater may be used in
combination potable water/space heating system. Do not use
in a space heating only application.
Toxic Chemical Hazard
WARNING
• Do not connect to non-potable water system.
Read Before Proceeding
CAUTION:
Keep safety your first priority. Take all pre-
cautions to avoid creating a fire, health or
safety hazard.
The following requirements must be met for the installation
of Combo Heating Systems:
1. All components used for the distribution of water in the
heating loop must be suitable for potable water. These
include all piping, fittings, solder and fluxes, pumps for
circulation of water, valves, etc.
2. The water heater must not be connected to a hydronic
heating system that has been used previously with non-
potable water.
3. No boiler treatment chemicals of any kind shall be
introduced into the system.
4. The Combo System components must be selected
and sized to meet and maintain the total calculated
demands for both domestic service hot water and space
heating requirement. The sizing and installation must be
performed in accordance with good engineering practice
such as “ASHRAE Handbooks”, HRAI, “Hydronics
Institute Manuals”, B139, NFPA 31, ANSI Z223.1,
CSA F280, National/Provincial Building Codes, CSA
C22.1, ANSI/NFPA 70, CSA B51 and/or codes having
jurisdiction.
