Inspect system water piping
After filling the boiler and system with water, INSPECTPALL PIPING throughout the system for leaks. If found, repair immediately. Repeat this inspection after the boiler has been started and the system has heated up.
,EAKSAMUSTSBE REPAIRED AT ONCE
Failure to do so can damage the boiler, resulting in substantial prop- erty damage.
$O NOTO USES PETROLEUMBASED
CLEANINGN OR SEALINGL COMPOUNDS in boiler system. Severe damage to boiler will occur, resulting in sub- stantial property damage.
Inspect base insulation
The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on PAGE of this manual. Failure to comply could result in severe personal injury.
&AILURE TO REPLACE damaged insu- lation or reposition insulation can result in a fire hazard, causing severe personal injury, death or substantial property damage.
#HECKETO MAKE SURE BASE INSULATION IS SECURE against all four sides of the base. If insulation is damaged or displaced, DO NOT operate boiler. Replace or reposition insulation.
