To provide close clearances as described in pages 26 and 27, Close Clearance Kit,
Close clearance installation:
Substitute these instructions for corresponding material in manual. All other procedures and practices must remain the same.
Recommended service and minimum clearances shown on page 4 should be used where possible. Where closer clearances are required:
•Top of boiler — If less than 24" available, provide removable surface to allow for cleaning boiler flueways.
•Right or left side — Minimum 2 inches.
•Front — Minimum 2 inches from burner.
•Doublewall flue pipe to combustible surface — as listed in Table on page 27 and FIGURES 19 through 21.
Jacket cap must be in place on boiler to avoid requiring an 18"
minimum clearance from back or top of boiler to combustible material. Flue pipe clearances must take precedence over jacket clearances.
1.Install boiler using clearances described at left.
2.Install barometric control
3.Attach manual reset temperature switch near upper surface of enclosed area. See FIGURE 17.
4.Wire switch in series with thermostat. See FIGURE 18.
5.Provide two combustion/ventilation openings when installing in confined space. Size opening 140 sq. in. (1000 Btu) per 1 GPH input. Locate openings near top and bottom of enclosed space.
