18 Owner’s Manual for Indirect Fired Heater
Maintenance
Adding Coolant
Coolant must be changed every year or at 1000 hours of
operation. Check coolant level and degree of fouling
according to the steps below. Correct coolant level is
approximately 0.39 in (10 mm) below the radiator core
top.
NOTE: Wear the proper PPE when handling Long Life
Coolant.
1. Verify engine is stopped and cooled.
2. Verify the drain plug is closed.
3. Remove radiator cap.
4. Fill radiator slowly with coolant until it reaches the
lip of the filler port.
5. Replace radiator cap.
6. Remove cap from the sub-tank.
7. Fill the sub-tank with coolant until it reaches the
FULL mark.
8. Replace sub-tank cap.
9. Operate engine approximately five minutes at a
low idle speed to purge the air in the coolant sys-
tem.
NOTE: Coolant level will drop.
10. Stop the engine and, once cooled, replenish with
coolant until the sub-tank reaches the FULL mark.
Maintenance Schedule
The following is the manufacturer’s recommended main-
tenance schedule. The maintenance items need to be
performed more frequently if the heater is used in severe
applications (such as very high or very low ambient con-
ditions or extremely dirty/dusty environments). Use the
heater hour meter or calendar time, whichever occurs
first, from the previous maintenance interval to determine
the next required maintenance interval. Note that some
checks are based on hours of operation.
Follow all applicable safety alerts found in this manual or
engine service manual before performing any mainte-
nance checks or service.
This maintenance schedule reflects the minimum tasks
needed to verify the heater remains operational. Some of
the tasks can be performed by an authorized operator,
and others must be performed by a GMP ASD.
NOTE: An authorized operator is one who has been
trained by a GMP ASD in proper operation and inspec-
tion of this unit.

coolant. Doing so will result in death or serious
injury.
WARNING
Risk of burns. Contents under pressure.
Do not remove the radiator pressure cap
while engine is hot. Doing so could result
in death or serious injury.

CAUTION
Do not use any chromate base rust inhibitor with
propylene glycol base antifreeze, boosters or additives.
Doing so will cause overheating.
