Installation Guide

11
1.  The vent damper must be the same size as the outlet 
of the Draft Hood supplied with the boiler (see 
Table 1A). Unpack the damper carefully - DO NOT 
FORCE IT CLOSED! Forcing the damper may 
damage the gear train and void the warranty. 
2.  Mount the vent damper assembly onto the canopy/
diverter. (Refer to Figure 7 and to instructions 
packed with the vent damper for specic 
instructions). Do not modify either the draft hood or 
vent damper.
NOTICE
Provide adequate clearance for servicing.
3.  Locate vent damper position indicating means to be 
visible following installation.
WARNING
Provide 6" minimum clearance between damper 
and combustible construction.
4.  Plug the factory harness vent damper connector into 
damper motor polarized receptacle.
DANGER
Inspect existing chimney before installing boiler.  
Failure to clean or replace perforated pipe or tile 
lining will cause severe injury or death.
D.  Inspect chimney and remove any obstructions or 
restric tions. Clean chimney if previously used for solid 
or liquid fuel-burning appliances or replaces.
E. Install vent system in accordance with "Venting of 
Equipment" of the National Fuel Gas Code, ANSI 
Z223.1/NFPA 54, or applicable provisions of local 
building codes. The RRG Series boiler is a Category I, 
draft hood equipped appliance. 
WARNING
F.  If an Existing Boiler is Removed:
  When an existing boiler is removed from a common 
venting system, the common venting system is likely 
to be too large for proper venting of the appliances 
remaining connected to it.
  At the time of removal of an existing boiler, the 
following steps shall be followed with each appliance 
remaining connected to the common venting system 
placed in operation, while the other appliances 
remaining connected to the common venting system are 
not in operation:
a.  Seal any unused openings in the common venting 
system.
b.  Visually inspect the venting system for proper 
size and horizontal pitch and determine there is no 
blockage or restriction, leakage, corrosion, and other 
deciencies which could cause an unsafe condition.
c.  Insofar as is practical, close all building doors and 
windows and all doors between the space in which 
the appliances remaining connected to the common 
venting system are located and other spaces of the 
building. Turn on clothes dryers and any appliance 
not connected to the common venting system. 
Turn on any exhaust fans, such as range hoods and 
bathroom exhausts, so they will operate at maxi mum 
speed. Do not operate a summer exhaust fan. Close 
replace dampers.
d.  Place in operation the appliance being inspected. 
Follow the Lighting (or Operating) Instructions. 
Adjust thermo stat so appliance will operate 
continuously.
e.  Test for spillage at the draft hood relief opening after 
5 minutes of main burner operation. Use the ame 
of a match or candle, or smoke from a cigarette, 
cigar or pipe.
f.  After it has been determined that each appliance 
remain ing connected to the common venting system 
properly vents when tested as outlined above, return 
doors, win dows, exhaust fans, replace dampers and 
any other gas-burning appliance to their previous 
condition of use.
g.  Any improper operation of the common venting 
system should be corrected so the installation 
conforms with the National Fuel Gas Code, ANSI 
Z223.1/NFPA 54. When resizing any portion of 
the common venting system, the common venting 
system should be resized to approach the minimum 
size as determined using the appropriate tables in 
Chapter 13 of the National Fuel Gas Code, ANSI 
Z223.1/NFPA 54.
