   Low-pressure steam boilers

	Daily:
		* Monitor general conditions
		* Monitor water level
		* Monitor operating pressure
		* Examine gage glass or water column 
		* Determine and correct cause of unusual noises 
		  or conditions
		* Examine water condition and perform corrections 
		  as necessary (add chemicals, blow down, etc.)
    
	Weekly:  

		* Examine low-water fuel cutoff
		* Blow down boiler
		* Monitor condition of flame
		* Check oil supply
		* Monitor operation of condensate or vacuum pump

	Monthly: 

		* Lift lever on safety valve 
			***Experience shows that safety valve seals often
			***leak once tested.
			***We suggest replacing safety valves every 5 years
			***instead of testing them.
			***Note: your boiler inspector or code may not allow
			***this.
		* Examine flame-detection devices
		* Examine limit controls
		* Examine operating controls
		* If required perform sludge blow down 
		* Verify condition of heating surfaces for oil pre-heaters
		* Verify combustion air supply to boiler room

	Annually:

		* Check internally and externally after cleaning
		* Open and inspect low-water fuel cutoff
		* Conduct routine burner maintenance
		* Conduct routine maintenance of condensate or 
		  vacuum return equipment
		* Conduct routine maintenance of all combustion 
		  control equipment
		* Combustion test
		* Draft test
		* Safety valve pop-off test
		* Low-water fuel cutoff evaporation test
		* Check gas/oil piping for proper support and tightness
		* Check boiler room ventilation louvers and intake

		* Monitor operation of circulating pumps

	Monthly:

		* Lift lever on safety valve 
			***Experience shows that safety valve seals often

		* Conduct routine burner maintenance
		* Conduct routine maintenance of circulation 
		  pump and expansion tank
		* Conduct routine maintenance of entire combustion 
		  control equipment
		* Combustion test
		* Draft test
		* Open and inspect low-water fuel cutoff
		* Check gas/oil piping for proper support and tightness
		* Check boiler room ventilation louvers and intake

	Every five years:

		* Internal inspection after cleaning
