*Rating at 100 psi. Sizing based on appliance maximum input rate not actual firing rate. **Do not exceed maximum BTU/HR input rating or maximum oil
GPH input. For multiple venting system applications, add the input for each appliance. Category I gas-fired draft induced systems require an SWGII-4HD
or larger. Category III gas-fired draft induced systems require an SWGII-5 or larger.
