Verifi cation of Torque Settings on Fireside Access
Doors
NOTE: ´ This section is relevant to Models VTG-4000LE, VTG-4000DF, VTG-5000DF,
and all standard VTG-4000 and VTG-5000 units starting with National Board #

There are two access doors to the  reside of the heat exchanger of the above
referenced Vantage models. There are a series of bolts on each door that must
be checked for torque every 2,500 operating hours, or once per heating season
(whichever is more frequent).
Proceed as follows:
1. Remove the boiler jacket panels (upper and lower) on the front of the
boiler.
2. Verify settings of the upper door. The upper door is retained by (4) 1-1/8”
bolts. Tools required for upper door setting veri cation:
§ 1-13/16” socket and ¾ x ½” adapter (these were provided from
the factory and should be stored in a safe place in the boiler
room). If these components have been misplaced, please
contact Fulton to purchase replacement components. The
Fulton part numbers are 2-22-000570 (socket) and 2-22-000571
(adapter).
§ ½” drive torque wrench and extension (provided by service
technician)
NOTE: ´ The upper door has a mass of approximately 140 lbs. Do not remove
the (4) bolts or door without guidance from the factory with regards to proper
procedures for accessing the  reside of the heat exchanger.
3. Evenly tighten all 4 bolts on the upper door in three stages:  rst to 20 ft/
lbs, then to 35 ft/lbs, then to 50 ft/lbs in the following criss-cross pattern:
top left, bottom right, bottom left, top right. Recheck all bolts in a circular
pattern. See Figure 15.
4. Verify settings of the lower door. The lower door is retained by (16) 9/16”
bolts. Tools required for lower door setting veri cation:
§ 9/16” socket and 3/8” drive wrench (provided by service
technician)
5. Evenly tighten all 16 bolts on the lower door to 23 ft/lbs in a criss-cross
pattern. See Figure 15. Do not over torque, as this can result in damaging
of the door seal.
