Venting
A check for correct venting of combustion products must be made before the installed heater is left
with the customer. The test should be made in the following manner.
Light the heater.
Turn the gas control to the
ON
position and thermostat to the highest setting.
After the appliance has been alight for five minutes place smoke match or taper inside the opening
in the B-vent adapter box. See figure below.
The installation is satisfactory if the smoke is drawn into the adapter box and up to the vent pipe.
If the vent is blocked or has strong reverse flow, the thermally actuated switch mounted in the adapter
box will automatically shut off the gas supply within about ten minutes. If the smoke is not drawn in,
leave for about ten minutes and then try again.
If the smoke is still not drawn into the adapter and vent pipe, turn the heater off and check cause of
lack of draft, if necessary get expert advice.
