Before Each Use:
■
Check to make sure the brood heater’s
surrounding area is kept clear and free
from combustible materials, gasoline,
and other fl ammable vapors and liquids.
■
Regulators must be periodically inspected to make
sure the regulator vents are not blocked. Debris,
insects, insect nests, snow, or ice on a regulator
can block vents and cause excess pressure at the
appliance.
■
Check all hose and tubing assemblies for cracks,
cuts, abrasions or ruptures. Replace any hoses that
are suspect.
■
Check all gasketing on burner box and fan housing
discharge. Ensure all is in good condition. Replace
any gasket material if suspect

Ensure re
fl
ector supports and hangers are secure,
re
fl
ectors do not sag, and are properly located.
■
Check overall condition of heater for cracked or
damaged components, loose screws or bolts,nicked
or cut electrical leads, etc. Replace any suspect
components.
■
For safety as well as for optimum performance of the
brood heater, it is necessary to keep the outside of
the brood heater free of dust, dirt or any combustible
material. If any operational component shows signs of
rust or corrosion, replace the component immediately.
■
Check all warning or instruction labels, dataplates,
etc. If any are lost or become hard to read, replace
them immediately. Do not operate the brood heater
until you have all instructions and can read and
understand them.
Annually:
■
Check the air inlet assembly. Ensure the air inlet as-
sembly and its duct are free of blockages.
■
Have your gas supplier check all gas piping for leaks
or restrictions in gas lines. Also, at this time have
your gas supplier clean out the sediment trap at the
inlet of the burner box of any debris that may have
accumulated.
■
Regulators can wear out and function improperly.
Have your gas supplier check the date codes
on all regulators installed and check delivery
pressures to the appliance to make sure that the
regulator is suitable for continued use.
