Installation; Part List - COZY PILOT PRO Series Installation And Operating Instructions Manual

Step 1
appliance installation as a preliminary step to applying an automatic intermittent pilot system.
The following procedure is intended as a guide to aid in determining that an appliance is properly installed
and is in a safe condition for continuing use.
This procedure is predicated on central furnace and boiler installations equipped with an atmospheric gas burner(s)
and not of the direct vent type. It should be recognized that generalized test procedures cannot anticipate all
situations. Accordingly, in some cases, deviation from this procedure may be necessary to determine safe
operation of the equipment.
A. This procedure should be performed prior to any attempt
at modification of the appliance or the installation.
B. If it is determined there is a condition which could
result in unsafe operation, the appliance should be
shut off and the owner advised of the unsafe condition.
The following steps should be followed in making the
safety inspection:
1. Conduct a gas leakage test of the appliance piping
and control system downstream of the shutoff
valve in the supply line to the appliance.
2. Visually inspect the venting system for proper size
and horizontal pitch and determine there is no
blockage or restrictions, leakage or corrosion or
other deficiencies which could cause an unsafe
condition.
3. Shut off all gas to the appliance and shut off any
other fuel-burning appliance within the same room.
Use the shutoff valve in the supply line to each
appliance. If a manual gas valve is not in the gas
supply line within 6 feet (1.83 mm) of the appliance
in an accessible location one shall be installed.
4. Inspect burners and crossovers for blockage &
corrosion.
5. Applicable only to warm air heating appliances.
Inspect heat exchangers for cracks, openings or
excessive corrosion.
6. Applicable only to boilers. Inspect for evidence of
water or combustion product leaks.
7. Insofar as is practical, close all building doors and
windows and all doors between the space in which
the appliance is located and other spaces of the
building. Turn on clothes dryers. Turn on any
exhaust fans, such as range hoods and bathroom
exhausts, so they will operate at maximum speed.
Do not operate a summer exhaust fan. Close
fireplace dampers. If after completing Steps 7

through 12, it is believed sufficient combustion air
is not available, refer to 1.3.4 of the National Fuel
Gas Code (Z223.1) for guidance.
8. Place in operation the appliance being inspected.
Follow the lighting instructions. Adjust thermostat
so appliance will operate continuously.
9. (a) Determine that the pilot is burning properly
and that main burner ignition is satisfactory
by interrupting and reestablishing the
electrical supply to the appliance in any
convenient manner.
(b) Determine manifold pressure in order to match
input after the new control is installed.
10. (a) Visually determine that main burner gas is
burning properly: i.e. , no floating , lifting or
flashback. Adjust the primary air shutter(s)
as required.
(b) If appliance is equipped with high and low flame
control or flame modulation, check for proper
main burner operation at low flame.
11. Test for spillage at the draft hood relief opening
after 5 minutes of main burner operation. Use
a draft gage, the flame of a match or candle, or
smoke from a cigarette, cigar or pipe.
12. Return doors, windows, exhaust fans, fireplace
dampers and all other fuel-burning appliances to
their previous conditions of use.
13. Applicable only to warm air heating appliances.
Check both limit control and fan control for proper
operation.
Limit control operation can be checked by temporarily
disconnecting the electrical supply to the blower
motor and determining that the limit control acts to
shut off the main burner gas.
