CAMBRIDGE HEAT HTSB1 Use & Care Manual page 9

- A Type 1 compatible cylinder with a Type 1 cylinder valve has a back-check valve which does not
permit gas flow, until a positive seal has been obtained.
- The cylinder must be arranged for vapor withdrawal. It must also include a collar to protect the
cylinder valve. A safety relief device having direct communication with the vapor space of cylinder
must be provided. This will expel high pressure gas if the cylinder is overfilled or overheated which
could result in fire or explosion.
- All LP gas cylinders used with this appliance shall be constructed and marked in accordance with
the specifications for LP gas cylinders of the U. S. Department of Transportation (DOT) or the
National Standard of Canada, CAN/CSA-B339, Cylinders, Spheres and Tubes for Transportation of
Dangerous Goods; and Commission, as applicable; and shall be provided with a listed overfilling
prevention device.
- Read labels on the LP gas supply cylinder.
- Allow only qualified LP gas dealers to fill or repair your LP gas supply cylinder.
- After filling, have the gas dealer check for leaks and to see that the relief valve remains free to
function.
Hose and Regulator (included standard with the appliance)
The Type 1 connection system has the following features:
- The system will not allow gas to flow until a positive connection
has been made.
NOTE: The cylinder control valve must be turned off
before any connection is made or removed.
- The system has a thermal element that will shut off the flow of
gas in the event of a fire.
- The system has a flow limiting device which, when activated,
will limit the flow of gas to 10 cubic feet per hour.
- NEVER use the appliance without leak testing this connection.
LP (Propane) Gas Supply Connection
1. The tank valve should be in the "OFF" position. If not, turn the knob clockwise until it stops.
2. Make sure all burner valves are in the "OFF" position.
3. Always connect the gas supply regulator as follows:
Insert the regulator inlet into the tank valve and turn the coupling nut clockwise until the coupler
tightens up (see picture). Do not over tighten the
coupler. Turn the main tank valve on and turn
the burner control valves on the unit to the
"HIGH" position for about 20 seconds to allow
the air in the system to purge before attempting
to light the burners.
WARNING:
Always take a leak test before lighting the appliance to prevent a possible fire or explosion.
Never store a spare propane cylinder in the vicinity of this appliance, or in the vicinity of any other
potential heat source.
