Installation of drawer assembly,
front base panels –
1. See Figure 6. Fasten front base panel (
6
Z\,
inch high)
and rear base channel to section assembly. Seal with
boiler cement along top of insulation panels.
2. The burner drawer assembly consists of the burner
drawer, main burners, gas manifold, pilot burner,
etc.
3. Check for proper orifice sizing from Table 3, page 7
in GSA boiler manual.
Proper orifices must be used. Failure to
do so will cause severe personal injury,
death or substantial property damage.
4. Place burners in the drawer assembly as shown in
Figures 7 and 8.
5. Slide the drawer assembly under the front base
panel and attach to the section assembly as shown
in Figure 9.
6. Level and straighten burners.
Burners must be properly seated in slots in
back burner support with openings facing
up. Gas orifices must inject down center
of burner. Failure to properly seat burners
will result in severe personal injury, death
or substantial property damage.
7. Install rollout thermal fuse element with wire termi-
nals facing up on front access panel as shown in
Figure 10. Wire per the appropriate Control Supple-
ment.
Inspect burners –
GSA 300 boiler
1. All units except GSA‑300 are factory‑assembled, but
the burners and base panels should be inspected to
ensure they are in good condition.
2. Remove the access panel (Figure 10) and inspect
the burners per step 6 above. Replace the access
panel.
Installation of flue collector hood
(Factory installed on GSA boilers up to GSA-300)
Set flue collector hood on boiler as shown in Figure 4. Use boiler
cement furnished to provide gas‑tight seal.
Failure to maintain gas‑tight seal can cause flue gas
spillage and carbon monoxide emissions, resulting
in severe personal injury or death.

Installation of rear base panels
(Factory installed on GSA boilers up to GSA-300)
See Figure 5. Fasten rear base panel (
7
B\zn
inch high) and rear
base channel to section assembly. Seal with boiler cement along
top of insulation panels.
Failure to maintain gas‑tight seal can cause flue gas
spillage and carbon monoxide emissions, resulting
in severe personal injury or death.
