. If the S30 has been installed at an altitude higher than 2000ft (610m) it is required to de- estIng rate the unit accordingly: In the USA: The appliance may be installed at higher altitudes. Please refer to your American Gas Association guidelines which state: the sea level rated input of Gas Designed Appliances installed at elevations above 2000 (610 m) feet is to be reduced 4% for each 1000 feet (305 m) above sea level.
• Locate the stove in a large and open room that is centrally located in the house. This will optimize heat circulation and comfort. • As the S30 is equipped with a convection fan, ensure that an electrical outlet is within 6 ft (1.8 m) of the stove.
If desired, the S30 can be converted from a top vent to a rear vent unit by following the steps below. Note: When converted to rear vent the S30 has a smaller range of allowable venting, refer to I nItIal before final installation.

Initial Installation QUALIFIED INSTALLERS ONLY LLowabLe onfiguRations Figures 26.1 and 26.2 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.
When installing the S30 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. Using the pair of air restrictors supplied with the unit, install them on each side of the firebox and adjust to the correct setting as outlined in the figure and table below.
Initial Installation QUALIFIED INSTALLERS ONLY oRizontaL eRmination NOTES: 1. Horizontal pipes must not be level. For every 12 inches (305 mm) of horizontal travel (away from the stove), there should be at least ¼ inch (6.4 mm) of vertical travel. Never allow the vent to run downward, as this could cause high temperatures or even present the possibility of a fire.
