8.  Install black plastic rings into 1-3/32 inch diameter 

holes located below upper louvers of front 

removable door.

9.  Install front removable door by engaging upper side 

edges of panel with side receiving flanges, sliding 

up and under top panel flange - seating front door 

fully - then sliding down to engage bottom flange 

behind lower front tie bar. 

Figure 10: Combustion Chamber

G.

 

Install Pilot/Burner Assembly

  (shipped in Gas 

Controls Carton).  See Figure 10.
1.  Remove jacket front removable door. 

a.  Remove burner access panel located above 

burners.

b.  Install Pilot/Burner Assembly where noted on 

gas manifold.

i.

  Insert rear of burner in burner tray slot.

ii.

  Position burner over the orifice.  

 

NOTE:  The burner to the right may need to 

be lifted from the orifice to install pilot/

burner assembly.  Reinstall lifted burner 

over the orifice.

c.  Reinstall burner access panel.

H.

 

Install Gas Valve

 on main gas burner assembly (if not 

factory assembled). See Figure 11, 12 or 13.
1.  Connect gas valve to manifold. 
2.  Connect pilot tubing from pilot burner to gas valve 

pilot tapping.

3.  Continuous Ignition (standing pilot): connect 

thermocouple to gas valve. 

I.

 

Install Blocked Vent Switch 

with sheet metal screws.

1.  Models IN3I - IN9I. Install on rear flange of canopy. 

See Figure 14.

2.  Models IN10 - IN12. Install on right side of draft 

hood. See Figure 15. Reset switch must face away 

from draft hood relief opening.

3.  Attach black 18-2 harness to Blocked Vent Switch 

terminals. Use end with two fully insulated 

disconnects.

4.  Secure harness to right side jacket panel with clamp.
5.  Insert harness through ¾ inch hole in right side 

jacket panel. Secure with strain relief bushing.

 II.  Knocked-Down Boiler Assembly (continued)
