Basic construction and options
Serial no. (If known or previously ordered)
Gap (if other than factory minimum)
Lead length (If other than std. 12")
Maintenance and trouble shooting for prolonging heater life
1. Regulate Voltage. A 10% variation in voltage results in a 20% variation in power.
2. When attaching the lead wire to the terminals, excessive turning pressure can cause breakage of the terminal resistance wire.
3. A ¼" gap should be maintained at the opening when operating. Retightening is not normally required, however, if the operating temperature is changed the clamp bolt should be checked.
