. Failure to prevent the boiler pipes from
turning could damage pipes, resulting in possible severe
personal injury, death or substantial property damage.
Pressure test the boiler before permanently attaching water or gas piping
or electrical supply.
1. Install the (Item 5a) two 1½” reducing tee (EVG 220 model) or two
1½” tees (EVG 299/300 & 399 models), and close nipple shipped
loose with the boiler, located and oriented as shown in Fig-
ure6,page11 and Figure7,page11, on the boiler supply and return.
2. Install the (Item 5b) one 1¼” NPT tee on EVG 220 or 1½” NPT tee on
EVG 299/300/399) and close nipples shipped loose with the boiler,
located and oriented as shown in Figure6,page11 on the boiler supply.

1. e following piping components (supplied by installer) are required
for the test conguration:
a. Two isolation shut-o valves (1¼” NPT on EVG 220; 1½” NPT on
EVG 299/300/399).
b. 1¼” NPT or 1½” NPT pipe nipples as shown in Figure7,page11.
c. ¾” NPT pipe plug.
2.
TEMPORARILY insert a ¾” NPT pipe plug in the relief valve tapping.
Aer the hydrostatic test, this plug must be removed and the relief
valve must be installed.
3. Install Pressure/Temperature gauge into the tee (Item 5b) as shown in
Figure7,page11.
1. See Figure6,page11 for use with the following instructions.
2. CLOSE boiler drain valve (item12). Connect a hose to fresh water
supply and to the drain valve.
3. Place a bucket under the ends of Isolation shut-o valves (item10 and
item11) to catch water drippage.
4. CLOSE isolation valve 11. (Return)
5. OPEN top isolation valve 10. (Supply)
6. Slowly open boiler drain valve (item12) and fresh water supply to ll
boiler with water. e boiler and internal piping will ll quickly because
of the low water content.
8. If upper spacer board is used, install the lower
spacer board as shown in Figure5,page9.
9. Once the wall-mount bracket is installed,
measure 35” below the bottom edge of the
bracket and strike a line or place a piece of
masking tape with the top edge even with the 35”
mark. is line will indicate if the boiler has been
properly seated in the hanging bracket.
10. Obtainassistancetolifttheboilerinto
position.
Theboilerisheavy, and requires
two people to li and place. Wear
non-slip rubber gloves to prevent pos-
sibility of cuts from sheet metal edges.
e jacket door can be le on boiler,
but boiler must ONLY be lied from
the bottom and rear of the sheet metal
housing, NOT from the pipes or any
plastic part.
11. Li the boiler high enough that its rear bracket
(item4, Figure5,page9) will be above the wall-
mount bracket.
12. Slide the boiler down so that the back of the cabi-
net is in contact with the lag screw heads until
t
he bottom of the boiler is below the line or tape
placed in Step 9. If necessary, move boiler le or
right until the tabs on the wall-mounting bracket
insert into the back of the cabinet.
When mounting the boiler, use the
method described in Step 9 to ensure
the cabinet is fully seated on wall
mounting bracket. If the bracket is
not fully engaged, the boiler could fall.
Failure to comply could result in severe
personal injury, death, or substantial
property damage.
