E. Hand Hole Plate Removal & Re-Installation
1.
Disconnect all power to the boiler.
2.
The boiler must be cool and drained of all water.
3.
See assembly print for hand hole location.
4.
Remove the hand hole plate nut. Use a 7/8" socket.
5.
Remove arch over hand hole plate.
6.
Remove hand hole plate. Sometimes it is necessary
to tap on the hand hole plate to loosen it. Make sure
the hand hole plate does not fall inside the boiler.
7.
Scrape the inside of the boiler around the hand hole
area to remove any scale or old gasket material.
8.
Scrape the old gasket material off the hand hole
plate.
9.
Make sure there are no burrs around the hand hole
opening. Remove any burrs with a file.
10.
Place the hand hole plate back into the boiler hand
hole plate opening without the gasket. If the plate
rocks back and forth, remove the high spots on the
hand hole plate with a file.
Note: Do not leave the
hand hole plate installed without the gasket.
11.
Install the gasket on the hand hole plate. Make sure
the gasket is pressed firmly down on to the hand
hole plate.
Do not use any grease, lubricants, or
adhesives when installing handhold gaskets.
12.
Reinstall the hand hole plate into the boiler.
13.
Replace the arch over the stud of the hand hole
plate. The arch should extend across the width
(short way) of the hand hole opening.
14.
Replace the nut on the hand hole plate stud.
Tighten the nut hand tight, then turn the nut ¼ turn
with a socket.
Do not compress the gasket
excessively.
This will only shorten the life of the
gasket.
15.
Reconnect the power to the boiler.
16.
Check the hand hole plate for leakage with
pressure on the boiler. If leaks are noted, remove
the pressure from the boiler, let the boiler cool and
drain to reposition the hand hole plate. Repeat
steps 12 through 16.
