Direct Vent Installation (Mandatory for models Lx150-400)
When installed as a Direct Vent boiler the combustion air-inlet must also be piped directly to the outdoors using
the methods described in this section and in accordance with the National Fuel Gas Code, ANSI Z223.1 (U.S.) or
CSA B149.1 (Canada) and local requirements.
Indoor Combustion Air (Optional for models Lx500-800)
When the installation uses Indoor Combustion Air (i.e. piping is not directly connecting the boiler air-inlet fitting
to the outdoors), provisions for combustion and ventilation air, in accordance with section “Air for Combustion
and Ventilation,” of the
National Fuel Gas Code, ANSI Z223.1/NFPA 54 (U.S.), or Clause 8.2, 8.3 or 8.4 of
Natural Gas and Propane Installation Code, CAN/CSA B149.1 (Canada), or applicable provisions of the local
building codes, must be adhered to.
The boiler shall be located so as not to interfere with proper circulation of combustion,
ventilation, and dilution air.
Make up air requirements for the operation of exhaust fans, kitchen ventilation systems,
clothes dryers, and fireplaces shall be considered in determining the adequacy of a space
to provide combustion air requirements. Failure to ensure adequate make up air to all
appliances may result in personal injury or death.
Controller RPM Adjustments – To avoid the potential boiler lockouts due to wind and
static pressure differences, the Lightoff and Minimum Modulation RPM Rates must be
adjusted as per Figures 4-11 and 4-21 in Appendix A when using indoor combustion air.
Air Filter Kit (P/N 84093) – When using indoor combustion air (non-Direct Vent), it is highly recommended to
use the optional Air Filter Kit (P/N 84093) to limit the amount of dust that enters the combustion system. The
Filter Kit can be installed on boiler models Lx500-800, as illustrated in Figure 4-1 (comprehensive
installation instructions are provided with the Filter Kit).
Venting Limitation – When using the Air Filter Kit on models Lx500-600, the maximum
equivalent exhaust vent length is limited to 30 ft. with 4” piping, or 90 ft. with 6” piping;
see warning below Table 4-5.
