improper operation.
Do NOT use this kit if the gas valve has a green label
(26,000 BTUH model) on it shown in Figure 10. The 26,000
BTUH model uses a different conversion kit available from
your distributor.
The 26,000 BTUH model uses a different conversion kit. Refer
to Product Specification for the correct conversion kit,
available from your distributor.
NOTE: Do not use this kit if the gas valve in Figure 10 has a
green label on top of the valve. The green label on the gas valve
