    Initial Installation QUALIFIED INSTALLERS ONLY LLowabLe onfiguRations Figures 32.1 & 32.2 show the range of possible vent configurations if the unit is top or rear vented, for vertical and horizontal terminations. Any layout that remains within the shaded areas is acceptable. Having the fewest number of elbows is ideal, as they tend to disrupt air movement.

  • Page 28: Air Restrictor Settings

    When installing the S20I/ S20ID with 8ft (2.44M) or more of vertical venting it may be necessary to restrict the fresh air supply in the firebox to control the combustion and flame appearance.
