FLEXIBLE GAS CONNECTOR
WARNING
FIRE OR EXPLOSION HAZARD
IMPROPER INSTALLATION, ADJUSTMENT,
ALTERATION, SERVICE OR MAINTENANCE
CAN CAUSE DEATH, SEVERE INJURY
AND/OR PROPERTY DAMAGE.
There Is expansion of the radiant pipe with each firing
cycle and this will cause the burner to move with
respect to the gas line. This can cause an unsafe
condition if the gas pipe connection is not done in
strict accordance to the instructions.
A flexible connector of approved type is required.
United States - Use only the 1” inside diameter, 36”
long stainless steel flexible gas connector as
supplied by Combustion Research Corporation.
Canada – Use approved gas connector as outlined
in B149 Codes; Type 1, 1” inside diameter,
minimum 36” long. This hose is to be supplied by
the Installing contractor.
Install the flex connector as shown in the diagram below in
one plane, parallel with the radiant tube without sharp
bends, kinks or twists. This gas connector accommodates
the normal expansion of the system. Before connecting
the gas connector verify that all high-pressure testing has
been completed.
Do not high pressure test the gas piping with the burner
connected. Failure to follow these instructions can result
in property damage.
Check the pipe and tubing ends for leaks before placing
heating equipment into service. When checking for gas
leaks, use a soap and water solution, never use an
open flame. The loop of the gas flex MUST BE parallel
or in line with the radiant tube and burner tube.
The displacement as shown is for cold, non-firing
condition. This displacement will vary as system heats
up.
Install drip leg in accordance with all applicable codes.
EXCESSIVE TORQUE ON THE BURNER GAS INLET
MANIFOLD MAY CAUSE DAMAGE. ALWAYS USE
TWO (2) WRENCHES WHEN MAKING PIPING
