Tjernlund SS2G SideShot (Discontinued) 8504075 Rev 1 11/98 - Manual (Page 4)

Disconnect the power supply when making wiring connections or when working around the fan wheel and motor. Failure to do so
can result in electrical shock, personal injury, death or property damage.
1. “Qualified Installer” shall mean an individual properly trained and licensed.
2. Plan the vent system so that Code required distances are maintained from plumbing and wiring.
3. Make certain the power supply is adequate for the fan motor requirements. Do not add the Power Venter to a circuit where the
total load is unknown.
4. The installer must verify that the BTU/hr. input of the appliance does not exceed the recommended input of the SS2G. See
Application Table on page 1 of these instructions for sizing information.
5. Flue gas temperatures must not exceed 650 degrees F at the Power Venter inlet. Ambient temperatures must not exceed 104
degrees F. Temperatures above this range can cause a fire resulting in property damage, personal injury or death.
6. “Safety inspection of a previously used gas appliance” as outlined below must be performed before installation of the SS2G as
outlined in ANSI Z223.1/NFPA #54, Appendix H.
7. The electrical load controlled through the Fan Proving Switch must not exceed the electrical ratings marked on the Fan Prover.
*SAFETY INSPECTION OF A PREVIOUSLY USED GAS APPLIANCE
(Perform prior to SS2G installation)
The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in safe condition
for continuing use.
The following procedure is based on central furnace and boiler installations and it should be recognized that generalized proce-
dures cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to determine
safe operation of the equipment.
a. Perform this procedure prior to any attempt at modifications of the appliance or installation of the SS2G.
b. If it is determined there is a condition which could result in unsafe operation, shut off the appliance and advise the owner of the
unsafe condition.
Follow the steps below 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 and determine there is no blockage or restriction, leakage, corrosion and other deficiencies
which could cause an unsafe condition.
3. Shut off all gas to the appliance(s).
4. Inspect burners and crossovers for blockage and corrosion.
5. Applicable only to furnaces: Inspect heat exchanger for cracks, openings or excessive corrosion. Check both the limit control
and fan control for proper operation.
6. Applicable only to boilers: Inspect for evidence of water or combustion product leaks. Determine that the water pumps are in
operating condition. Test low water cutoffs, automatic feed controls, pressure and temperature limit controls and relief valves in
accordance with the manufacturer's recommendations to determine that they are in operating order.
