SL Series gas-fired modulating boilers are low pressure, fully condensing units having
variable input ranges (see specification chart - inside, front cover). Approved as "Category
IV" vented appliances, the boilers use either Direct Vent (sealed combustion) or indoor
combustion air, providing a great degree of installation flexibility.
Figures 1a,and 1b show outer case dimensions and piping and electrical holes. Refer to
the applicable diagrams to help find a suitable location for the boiler. See also Section 1.3
