Propane tanks are at pressures that will cause damage to valve components. Verify that the tanks have step down
regulators to reduce the pressure to safe levels.
Using a propane tank smaller than 100 lbs may create pressure loss and insufficient fuel delivery, which can cause
sooting, severe delayed ignition, or other malfunctions (see NPFA 58).
Any damage as a result of insufficient tank size or other improper installation is NOT covered under the limited
warranty.
The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during
any pressure testing of that system at test pressures
in excess of
1/2 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its equipment shutoff valve during
any pressure testing of the gas supply piping system at test pressures
equal to or less than
1/2 psi (3.5 kPa).
