Thanks to Qamar who found these two verses on ETS in Ch. 3. I completely missed these two myself but managed to find them in Ch 4 (after completely doubting my earlier opinion that Ch 4 lacked any references to ETS). Anyhow, here are ch 3&4:
3/106-107: A day where some faces will be whitened and others darkened. Those whitened will be with the rahmah of Allah and in that rahmah they are to dwell forever.
4:30: Soon Allah will cast them into fire
55: Hell/jahannam is a burning fire
56: Fire burning skins
57: Jannah tajri min tahti al-anhar, khalideen feeha abada(gardens under which rivers flow, they are dwellers in it forever)
169: Except the way to jahannam, khalideen feeha abada
