11.2 Annual Shut Down Procedure
• Follow instructions “To Turn Off Gas To Appliance” unless
boiler is also used to supply domestic hot water. See
section 10.
• Drain system completely if system does not have
antifreeze when heating system is to remain out of
service during freezing weather.
• Drain condensate lines when boiler is to be exposed to
freezing temperatures.
WARNING
Following service procedures must be performed
by qualied service agent. Boiler owner shall not
attempt these steps. Failure to do so could result in
death or serious injury.

11.3 Annual Inspection and Cleaning of Boiler
Components
• Obtain Burner Inspection Kit. Follow kit instructions to
prepare for examination and cleaning.
• Burner and heat exchanger inspection and cleaning.
• Remove gasket and burner. Allow burner to clear top
lip of chassis.
• Remove any residual sleeve and/or gasket material
from removed burner.
• Clean burner using air hose directed into top of
burner opening to dislodge any debris in burner ports.
Inspect burner for foreign matter in ame ports or
inside burner. Remove foreign matter by blowing with
compressed air or vacuuming. Replace burner if it
cannot be cleaned or is showing deterioration.
• Clean heat exchanger with low pressure water spray.
Use exible handle nylon brush to loosen sediment
and oxide on all accessible heating surfaces of heat
exchanger. Take care not to get brush stuck in heat
exchanger.
• Remove any remaining loosened sediment using shop
vacuum with snorkel attachment.
• Clean condensate collector if signicant debris found in
heat exchanger.
• Expand upper spring tension clip of condensate trap
using hose clamp pliers. Disconnect condensate trap
from condensate collector. See gures 11-3 & 11-4.
• Disconnect wire harness from vent temperature
sen s or . Se e g u re 1 1- 3 .
• Loosen upper hose clamp securing condensate
collector to ue pipe using 3/8" socket with 6"
extension.
